State of the art

The present invention relates to devices for the separation of minerals, in particular, to an improved concussion concentration table, and more specifically, to improvements in flushing water collectors and decks of concentration tables to ensure the placement of magnetic separators and increase the yield of useful product and the quality of separation.

Tremendous concentration tables have been used for several decades. FLSmidth-Knelson Solutions uses a Knelson concentrator to enrich dense particles containing a valuable mineral. Further, this concentrate is supplied either to the ConSep ACACIA intensive cyanidation reactor (if cyanide is allowed to be used at the work site) or to a shaking concentration table. At the exit of the concentration table, fusible gold is usually obtained. For example, a description of the corresponding known systems can be found in any of US patents No.№: 2325340; 4,078,996; 4,150,749; 4,170,549; 4,251,357; 4,340,469; 4,758,334; 5160035; 5,205,414; 6,059,118; 6,155,707; 7,533,775; 4,758,334; 2,325,340; 4,326,951; 4340469 and 4347130.

The concentrate delivered to the shaking concentration table may contain fragments that form in a ball mill. These fragments create problems for enrichment / separation on a shaking concentration table, as large pieces of ferrous metal can act as smaller and denser particles of gold. As a result, the presence of such metallic impurities can easily disrupt and pollute the accumulation of gold on the shaking table. If the use of a magnetic drum separator at the input of the shaking table is undesirable, then a flat magnetic separator suspended above the active surface of the shaking concentration table can be used. However, in existing installations with shaking concentration tables, the space that could be used to accommodate suspended flat magnetic separators is very limited.

For example, conventional Gemini (Gemini) type shaking concentration tables use a large central water collector located on top and running along the length of the shaking table to supply flush water to the separating surface. Flushing water is necessary to flush out impurities to allow the concentration table to accumulate gold. In existing Gemini designs with a central water collector, the user needs to stretch across the surface of the working table to manually adjust each water nozzle in the center of the table, which, in turn, oscillates with the table and the central water collector. This is especially difficult for tables of large width, when it is difficult for a person to reach across the table to its middle, and there is a danger of disruption of the separation work of the concentration table. In addition, the existing nozzles / valves used on these large central water collectors located on top easily break or bend when trying to manually adjust them, especially during vibrations. It is also quite difficult for the operator to grab the oscillating nozzle / valve and perform any actions with it to quickly and accurately control the flow while optimizing separation in any part of the vibrating concentration table. Accordingly, a more robust and stable system is required in which the end user has the ability to more reliably control the flow of flush water supplied to or discharged from each nozzle.

In addition, since magnetic induction usually decreases rapidly as the magnetic device moves away from a given area, the planar magnetic separator should typically be located as close to the separating surface as possible to optimize the magnetic separation characteristics. In existing "Gemini" constructions, central large water collectors, nozzles, and sides located on top are all mounted high. As a result, they interfere with magnetic separation devices and do not allow them to be brought closer to the deck of the concentration table, reducing the overall separation efficiency of the entire installation of the concentration table.

In addition, in existing installations of shaking concentration tables in the area of sloping flooring / inclined water flow, a large amount of water may be in the process. A large amount of water can accumulate in front of the edges of the grooves, and, accordingly, in the process of operation, “standing waves” can form in the device, forming bypass routes (ie, “shunting” paths), along which the incoming loading material can easily go into error drive for tailings (waste). This is extremely undesirable, since valuable solid particles are found in the loading material, which will be lost. In existing Gemini-type devices, standing waves were observed approximately at a distance of 0.5 to 1.5 inches from the walls (moving parallel to the wall), while the solid particles, oscillating and floating up in these standing waves, move to the “tails” storage ring and do not get processed in the grooves of the concentration table.

It is clear that there are a large number of variable parameters that affect the resulting performance characteristics of the concussive concentration table. The features of the embodiments disclosed further in the present description have contributed to increasing the efficiency of gold recovery.

Objectives of the invention

Accordingly, it is an object of the invention to provide a mechanically durable, improved concussion concentration table providing efficient and high-performance enrichment to produce a fusible concentrate.

Another objective of the present invention is the improvement of existing collectors of flushing water and the geometry of the deck of the concentration table so that they are better combined with magnetic separators.

Another objective of the present invention is to provide a new design of the deck of the concentration table, optimized for use in conjunction with a closely spaced hanging upper flat magnetic separator.

Another objective of the present invention is a radical improvement in ergonomics and control capabilities during monitoring and precise adjustment by the user of the flow of flushing water to the deck of the shaking table, both in working and inoperative state.

Another objective of the invention is the creation of a fully automated system of the concussion concentration table, which is more secure by reducing unnecessary human contacts with the sections of the deck of the concussion table on which the concentrated product is located.

Another objective of the present invention is to provide a shaking concentration table system that re-enriches the “tails” and intermediate product on the shaking table deck to minimize losses and improve product recovery.

Another objective of the present invention is the creation of a periodic (batch) separation process, which can be modified to receive concentrate from one or more gravity concentrators or similar concentration devices.

Another objective of the invention is the creation of a competitive treatment option in which intensive cyanidation is not used and which, therefore, can be used when cyanide degradation is unavailable or not permitted.

Another object of the invention is to achieve a larger surface area compared to existing concentration tables with a central feed material feed.

Another object of the invention is to provide an installation of a concussive concentration table having surfaces with high abrasion resistance with increased mobility of particles and requiring minimal maintenance.

These and other objects of the invention will be apparent from the description below and the attached drawings. Although it is assumed that each objective of the invention should be solved in at least one of the embodiments of the invention, it is not necessary that in any embodiment, all the objectives of the invention are solved.

Disclosure of invention

The present invention provides the disclosure of a concussive concentration table. The shaking concentration table may include a table deck assembly having a loading end and a discharge end, at least one nozzle for flushing water, a low profile (slightly protruding) relative to the table deck assembly, and at least one external manifold of the flushing water distributor, functionally (during operation) ) associated with at least one nozzle for flushing water. The location and shape of the at least one external collector of the flush water distributor can be selected so that the operator does not need to reach through the table deck assembly. The location and shape of the at least one external collector of the flush water distributor may be selected so that the operator can easily control the flow of flush water to the at least one flush water nozzle. The shaker table may include one or more flushing water tubes extending between at least one flushing water nozzle and at least one external collector of the flushing water distributor. The loading end of the table deck assembly can be rounded to form an artificial dead zone, which distributes the material along the grooves on which it is processed, and eliminates the appearance of shunt paths that occur in conventional devices. In some embodiments, the loading end of the table deck assembly may be located above the discharge end of the table, resulting in an inclination angle of the table deck assembly of about 1-3 degrees. At the discharge end, the concentration table may have one or more canine-shaped outlet elements, the shape of which can improve the concentration at the discharge end. The shaking concentration table may have at least one flush water nozzle mounted separately on the table deck assembly. The shaker concentration table may also include a quick coupler between at least one wash water nozzle and at least one external collector of the wash water distributor. On top of the table deck assembly, there may be an upper magnetic separator, separated from the table deck assembly by an upper gap of less than 3.5 inches, which is less than the gap possible in conventional devices. In some embodiments, the shaking concentration table may comprise a centrifugal filter in front of at least one flush water nozzle to minimize clogging of the nozzle. In some embodiments, one or more external collectors of the flush water distributor may be located in easily accessible places at the edges, instead of being centrally located on the top of the table deck assembly. At least one external collector of the wash water distributor may comprise one collector or two external collectors of the wash water distributor. In some embodiments, each of the two external manifolds of the flush water distributor may be located on opposite sides of the table deck assembly of the vibratory concentration table. In other embodiments, each of the external collectors of the flushing water distributor may be located on the same side of the table deck assembly.

A method for controlling the operation of a tremulous concentration table is also provided. When implementing the method, a part of at least one external collector of the flushing water distributor is connected and the flow of flushing water in at least one nozzle for flushing water is regulated, not reaching it through the table deck assembly.

A nozzle assembly for flushing water is also proposed for the table deck assembly of the vibratory concentration table. The nozzle assembly for flushing water may have a cavity for the sealing ring and a housing, a clamping sleeve adapted to the outer diameter of the tube for receiving it, a central channel, and one or more nozzle openings intersecting the central channel. The flush nozzle may also have a mushroom shape. In some cases, the nozzle may have a flattened rounded head, low profile relative to the table deck assembly. The nozzle may have one or more surfaces of application of torque for orientation and (or) fixing, or tightening. In some embodiments, one or more surfaces of the application of torque may be in the form of faces or grooves. The nozzle holes can be located on one side of the nozzle for flushing water, thereby forming a one-way nozzle for flushing water, or the holes of the nozzle can be located on opposite sides of the nozzle for flushing water, thereby forming a two-side nozzle for flushing water.

More specifically, as one of the objects of the present invention, a shaking concentration table for placing an upper magnetic separator is claimed, comprising: a table deck assembly having a loading end and a discharge end; at least one nozzle for flush water having a mushroom shape, including a cavity for accommodating the sealing ring and a housing, a clamping sleeve adapted to the outer diameter of the tube, the central channel and one or more nozzle openings intersecting the central channel, and made low-profile relative to the deck assembly the table so that a reduced profile of the concussive concentration table and the possibility of placing the upper magnetic separator in the immediate vicinity of the table deck assembly are provided; and at least one external collector of the flushing water distributor operatively connected to said at least one nozzle for flushing water by means of a pipe for flushing water passing between said at least one nozzle for flushing water and at least one external collector of the flushing water distributor with the possibility for the operator to regulate the flow of flushing water to the specified at least one nozzle for flushing water from an external manifold of the flushing water distributor, said at least it least one external flush water distributor manifold is secured to the edge operator the possibility to regulate the flow of flushing water to said at least one nozzle for flushing water.

Detailed Description of the Invention

A description is given of the shaking concentration table 100 and separation system 60, mainly shown in the drawings. As shown in FIG. 1-11 and 13-19, the design of the table deck assembly 4 has a significantly lower lateral projection than conventional shaking concentration table devices. This is achieved by lower placement of outlet openings 50, 51, 52, 53 of the drain trays along the table edge, as well as a change in the design of the flush water distribution system due to the use of low-profile mushroom-shaped nozzles 29 for flush water located near the center line of the table 4 and passing sequentially or parallel to generally along the line from the loading end 56 to the discharge end 57. As shown, the nozzles 29 can be arranged by a matrix 54, and each of them can have a head 30 and a housing 31. This design is used instead of p The design of the Gemini-type water distributor tube (including the rather strongly protruding central manifold and nozzles / valves). The reduced side view of the shaking concentration table 100 improves the magnetic separation efficiency when used with an upstream magnetic separator, since the top magnetic separator can be located in close proximity to the deck 4 of the table. External collectors 17, 18, 66 of the flushing water distributor can be placed on the sides of the table (one on each side of the table, as shown in Fig. 1-19, or both on the same side, as shown in Fig. 20). In another embodiment, a single external manifold of a flushing water distributor 17, which serves both the left and right parts of the table deck 4, can be used. In such an embodiment, the flushing water nozzles 29 may be equipped with nozzle openings 32 located on both sides of the nozzle 29, or the matrix 54 may have alternating nozzle openings 32 facing left and right. To supply flush water to the parts of the deck 4 of the table, a series of flush water tubes 19 pass between the flush water manifolds 17, 18, 66 and flush water nozzles 29 forming the matrix 54. Each central flush water nozzle 29 can be connected to the corresponding external collector 17, 18, 66 of the distributor of flushing water with one pipe 19 for flushing water. The flushing water tubes 19 may comprise plastic or rubber water hoses ending with a mini hand valve screwed into the corresponding external manifold 17, 18, 66 of the flushing water distributor. The user can control the flow of flushing water to deck 4 of the table on either side or both sides of the shaking concentration table 100 and, at the same time, he no longer needs to reach through the top of the shaking table to the middle of the table to control the vibrating nozzle / valve. The upper surface of the table deck 4, which does not have large protrusions, allows, in particular, the use of an upper magnetic separator 69, for example, a tape magnet located in the immediate vicinity of the table deck 4.

The shaking concentration table 100 may include a welded support frame 1, a hinged support 2 of the rocker arm, a welded rocker plate 3, a table deck assembly 4 having several grooves 59, a molded boot material supply plate 5 that can separate from the table deck assembly 4 (and be interchangeable or interchangeable, depending on the type of boot material), a variable frequency drive (VFD) 6 for reporting a tremulous movement to the node 4 of the table deck, the motor 7 of the drive mechanism, functionally connected to the VFD 6 , an eccentric bushing 8, an insert 9 of the drive bearing, an adapter 10 of the drive, a weld spindle 11, an internal seat 12 of the spring, an external seat 13 of the spring, the drive spring 14, the drain hole 15 with a threaded sleeve and a cast shock absorber 16. The variable frequency drive 6 may have computer control that provides fine adjustment of the frequency of shocks of the deck 4 of the table, which can significantly improve the efficiency of product extraction. The overlay 5 for supplying the boot material can be shaped to provide for the dissipation of the energy of the boot material and the distribution of the boot material over a large area, which can inhibit the formation of a standing wave and the formation of shunt paths into the “tails”.

In some embodiments, the first manifold 17 of the flushing water distributor may be mounted on the left side of the table deck assembly 4, and the second manifold 18 of the flushing water distributor may be mounted on the right side of the table deck assembly 4. The shaking concentration table 100 may also include a first welded support of the collector 20, a second welded support of the collector 21, several drainage hoses 22 connected to several collecting trays 50, 51, 52, 53, a welded support 23 of the loading hopper, a welded bracket 24 of the hopper, welded hopper 25 and node 26 of the collector of the water filter. For screwing or securing the shaking table 100 in the system, a group of clips 27 can be used.

The shaking concentration table 100 may be connected to the water source via the herringbone connection fitting 28 for the water supply hose. The supplied water can be pre-filtered and then supplied to each nozzle 29 in the central matrix 54. Flushing water enters the central channel 33 inside each nozzle 29, which is connected to one or more holes 32 of the nozzle. Preferably, one or more nozzle openings 32 are specially arranged to supply flush water to predetermined portions of the table deck 4. In order to orient the holes 32 and “adjust” the supply of flushing water to specific places on the table 4, torque application surfaces 38, for example faces, slots, or grooves, can be used.

Tubes 19 for flushing water can be connected to each nozzle 29 through the cavity 39 in each nozzle. In the presented private embodiment, a sealing ring 34 is installed in the cavity 39, and the cavity 39 itself is plugged by a barrel-shaped insert 36. An elastic / snap-in clamping sleeve 37 is included in the insert 36, the inner diameter of which is selected so as to correspond to the outer size of the corresponding tube entering the sleeve 19 for flushing water. Similar quick couplings can be used between flushing water tubes 19 and manifolds 17, 18, 66. In other cases (not shown), each nozzle 29 may have a herringbone fitting or normal pipe thread or other equivalent pipe connection means.

As shown in the drawings, each flush water nozzle 29 may have, in particular, an external thread 35 that can enter a hole 55 in the blank of the table deck assembly 4. The nozzles 29 may be attached to the table deck assembly 4 with nuts on the other side. In another embodiment, the flushing water nozzles 29 may be glued or soldered into the holes 55 of the table deck assembly, or elastically snap into these holes. In yet another alternative embodiment, nozzle openings, including central channels 33 or nozzle openings 32, may be mechanically cut into protrusions molded into the table deck assembly 4 at points where holes 55 would otherwise be made. In this embodiment (not shown) in deck 4 of the table, holes 55 are not formed, and mechanically cut nozzles cannot be interchangeable or interchangeable, like nozzles 29 shown in the drawings. In addition, nozzle openings 32 may require more frequent cleaning if filtered flush water is not used.

At the discharge end 57 of the shaking concentration table 100, a discharge element 40, for example, one or more canine-shaped protrusions, can be placed to prevent sulfides from passing into the last concentrate tray 50, thereby increasing the level of separation of the concentrate. The concentrate tray 50 intercepts the most purified concentrate in the last outlet (i.e., outlet No. 8). The discharge element 40 moves the sulfide-containing materials to the tray 51 for intermediate products of the 2nd degree of purification (MIDS2), in which the concentrate of the second degree of purification obtained by the separation system 60 is collected. Upstream from the tray 51 of the MIDS2 there is a tray 52 for intermediate products of the first degree of purification ( MIDS1), which may have multiple outlets (e.g., outlets 4-6, as shown in the drawings). Materials collected in tray 52 of MIDS1 typically have a lower degree of purification than materials collected in tray MIDS2 and / or tray 50 for concentrate. Still further upstream, at the table deck assembly 4, there is a “tail” tray 53, which may have several outlets (i.e., outlets 1-3 shown in the drawings). The material collected in the tailings tray 53 may have a very low content of the target mineral and therefore may be disposed of, recycled, or sent to a different, coarser separation operation.

To supply energy to the variable frequency drive 6, a power supply 58 is used. As shown in FIG. 12, dividing the drainage holes / bowls of the shaking concentration table gives: TAILS - “tails” (lowest quality), first intermediate degree of cleaning MIDS1 (medium quality), second intermediate degree of cleaning MIDS2 (high quality) and CONC - concentrate (highest quality / fusible gold). The distribution of the recovered gold shows a marked improvement in the performance of the embodiments of the invention in comparison with a shaking concentration table of the Gemini GT1000 type. It has been found by the inventors that approximately 9% of the total gold recovered is expected to fall into sections 1, 2 and 3 of the “tails” during use, compared with approximately 24% in a conventional Gemini GT1000 type shaker table. It was also found that approximately 13% of all gold recovered is expected to enter sections 4, 5, and 6 of the first intermediate degree of purification, compared with approximately 39% in a conventional Gemini GT1000 table. In addition, it was found that approximately 22% is expected to enter section 7 of the second intermediate degree of purification, compared with approximately 28% for a conventional Gemini GT1000 table. It was also found that approximately 56% of all gold recovered is expected to enter section 8 of the concentrate, compared with only 9% in a conventional Gemini GT1000 table. It seems that an increase in the degree of purification of the final product obtained from the concentrate tray 50 is facilitated by the use of outlet elements 40 directing sulfides to section 7 of the second intermediate cleaning section.

In FIG. 13 shows that in order to reach the “tail” collection tray 53, the loading material, after contacting the molded feed supply plate 5, must pass over about 20 grooves 59 on which the material is processed. The loading material cannot bypass the grooves 59 along the shunt path, as is the case with existing structures with Gemini type table geometry. The rounded loading end of the shaking concentration table 100 typically prevents water shocks from the wall / standing wave, which typically occurs in a Gemini type table. This does not allow the loading material to oscillate and “pop up” in these standing waves, move to the “tail” tray 53, and / or bypass the grooves 59 on which the material is processed along a shunt path. However, if the supply of loading material to the table deck 4 is too fast, the loading material may also be at the rounded loading end 56, which may lead to the formation of a shunt path to the tray 53 of the “tails”.

In FIG. 15 shows sulfide diversion means 40, in accordance with some embodiments. The presence of sulfide inclusions required the use of a diverting element 40 for diverting sulphides into a tray 51 for a second intermediate product to prevent contamination of the concentrate in the pan 50. This diverting element 40 can be introduced into the described table deck assembly 4, in accordance with some uses of the invention .

In accordance with some variants of execution, the nature of the transition between the grooves / separation process can be made much more extended than in known devices. As a result, the processing area is increased, the processing geometry is expanded (for example, grooves and (or) separating transitions), and the geometry of the loading end is improved. The rounding of the loading end 56 eliminates any shunt passages through which the loading material can flow into the tails. To prevent the effect of direct sliding with the water flow, elongated grooves 59 can be introduced into the “tail” trays at the loading end, and the rounded shape of the loading end 56 prevents the occurrence of a standing wave. At the loading end of deck 4 of the table, additional transitions between the grooves can be introduced to improve separation. Additional grooves 59 can be used to increase the grade of more concentrate directed to tray 53 of the “tails” (ie, material that would otherwise be directed to one of the drain holes of 1-3 “tails”), directing it to the tray 52 for intermediate products of the first degree of purification (MIDS1) and / or tray 51 for intermediate products of the second degree of purification (MIDS2). The length of the separation area of the table deck 4 can also be increased to further increase the quality of the concentrate recovered in the concentrate tray 50.

In FIG. 16 shows a test of a shaking concentration table 100, in accordance with some embodiments. The test was successfully completed. The feed material was stopped, and the table was cleaned 2-2 minutes after the feed was stopped.

In FIG. 20 shows a separation system 60 including a new shaking concentration table 100 in accordance with the present invention. System 60 is similar to the system described in US 6818042 (incorporated herein by reference). System 60 includes a shaking concentration table 100 in accordance with the present invention, a screw feeder 61 for moving the loading material to the loading end 56 of the table deck assembly 4, a settling tank 62, a concentrate washing liquid supply point 63, a “tail” tank 64 with a pump, for removal of “tails” or their reprocessing on a shaking concentration table 100, lockable box 65 for gold concentrate, one or more easily accessible collectors 66 of the flushing water distributor, platform 67 for op iterator, magnetic tape separator 69, located in the immediate vicinity of the table deck 4 next to the loading end 56 of the shaking concentration table 100, a feeding funnel 70 to the loading material table, a user platform 71 and a sieve 72. In some embodiments, a sieve can be used SWECO sieve, which may be smaller than the required size for the shaking concentration table 100, but too large for the sump for the 64 tails with the pump. For example, in a particular example, sieve 72 may include a mesh vibrating sieve 20. In some embodiments, the magnetic separator 69 may be a 10 × 6 inch flat magnet having a moving conveyor belt and a scraper for cleaning. In other embodiments, a drum magnetic separator may be used.

In some embodiments, the described shaking concentration table 100 may have a variable push amplitude to adjust the extraction process. To change the dynamics of the movement of the device, the shaking table 100 may have an adjustable spring elasticity.

In some embodiments, flushing nozzles 29 may be individually controlled nozzles to provide finer control over flushing water. Nozzles 29 may have manual control, but may also have automated control using standard control valves associated with a control system having a central processing unit (CPU) or PLC. The CPU / PLC can have a functional connection with the mentioned combination of PLC / HMI, or can be part of it. In some embodiments, to improve the quality of the wash water, filtering thereof can be used, which will reduce the likelihood of clogging of the wash water nozzle 29. In such cases, the filtering means are installed up to nozzles 29 for flushing water, tubes 19 and / or collectors 17, 18, 66. In some embodiments, to improve

stability of movements of the deck 4 of the table, an accelerometer is used with reading readings through the HMI. In some embodiments, the deck 4 of the table may have a longitudinal angle of one to three degrees and, preferably, the longitudinal angle of approximately two degrees. To maintain the angle of the longitudinal inclination of the table, levels, inclinometers, digital level indicators, or an automatic leveling device can be used. In the simplest embodiments, a manual tilt meter can be used for initial installation. If the longitudinal tilt angles deviate from the optimal operating conditions or specified settings having a minimum and (or) maximum threshold value, audible alarm devices or equivalent signaling devices can be triggered to alert the operator to check the table orientation. The geometry of the table and the profile of the grooves 59 can be selected and optimized for maximum extraction efficiency of the precious metal, and the particular particular configurations shown in the drawings are presented for illustration only and do not limit the invention.
