" the fine disperse particles of heavy mineral " refers to that full-size is at 0.1 mineral microparticle that arrives in the 0.005mm scope;
" the laminar particulate of heavy mineral " refers to that thickness is substantially less than the mineral microparticle of its length and width;
" encirclement rock " refers to natural minerals, for example quartzy or artificial class mineral material, and artificial class mineral material is as the accessory substance of processing as compound (many metals) ore particularly slag or deposit that produce and that contain valuable heavy mineral mixture;
" soil " refers to the initial loose accumulation of mineral microparticle, for example preferably contains the quartz sand of valuable heavy mineral mixture;
" black heavy sand " refers to surround the disperse particles of rock, and density is near the density of valuable heavy mineral, for example:
Such natural minerals: magnetic iron ore and ilmenite, and/or
Such artificial mineral particulate: ferrous and lead shot tailing, converted steel particle, ferrous waste material or widely metallurgical production rubbish abandon other refuse that occurs in the field;

Usually known:
Initial valuable heavy mineral concentration in surrounding rock and soil is seldom greater than 1%, and the total valuable native metal in the ore in sand form be no more than usually 0.1% and
The pith of any valuable heavy mineral is deep-rooted in encirclement rock that disperses and/or soil with fine dispersion and/or thin slice particulate usually.
Therefore any hurley log washer and collection carpet veneer are necessary:
Make concentrate enrichment as far as possible with target product,
Produce and use simple and be easy to and change;
Be suitable for surveying and exploitation heavy sand ore deposit,
Provide processing safety, as far as possible circlet environment pollution and low power input factor.
These requirements are difficult to take into account.Therefore have only indivedual requirements or some combinations to be achieved so far.
In fact, two kinds of methods extracting precious metal from surround rock and soil are exactly known (Great encyclopedic dictionary POLYTECHNIC in 19th century, Moscow:Scientific PublishingHouse, Great Russian Encyclopaedia, 1998, p.25 and is p.591), these two kinds of methods are:
Amalgamation promptly by mercury dissolution of metals (preferred gold or palladium), separates amalgam by filtering with undissolved encirclement rock and/or native residue, and by the mercury evaporation target product is separated with filter liquor and
The cyaniding lixiviation process is promptly selected dissolving (preferred gold or silver) in the aqueous solution a little less than alkali metal hydride, deposit target product then.
These methods have gratifying power input factor, and it is no matter the shape and size of particulate provide the extraction of the precious metal almost completely from surround rock and/or soil.But it is very difficult and cost is very high that protection individual and environment are avoided the harm of such toxic material such as mercury and cyanide.In addition, the realization of described method and apparatus is of no use for the detection of placer.
Therefore amalgamation and cyaniding lixiviation process are generally used for coming industry to extract precious metal from the electric installation waste material or by the concentrate that obtains from placer ore pulp deposition now.
Compare with the encirclement rock under the gravitational field effect and/or the sedimentation rate of native particulate, these concentrate use the high relatively sedimentation rate of heavy mineral particulate that is included in the ore pulp to obtain usually.Dregs are by water or wash off (Shokhin V.N., Lopatin A.G., Gravitationmethods of enrichment, Moscow:NEDRA Publishing House, 1993) for other liquid stream from non-metal particle sometimes.
As the mechanical impurity of the encirclement rock that chemical change does not take place and/or native particulate and unsegregated heavy mineral residue, the concentrate of water base ore pulp, acquisition and the tailing of enrichment are inertia biologically.Therefore, any gravity is collected and is actually safe for miner and natural environment.
But because the density of the density of target product and encirclement rock and/or soil is approaching, the content of fine dispersion of valuable heavy mineral or thin slice particulate increases, so the effect that gravity is collected reduces.And, even target product and the density contrast that surrounds between rock and/or the soil are very big (for example, be similar to the density contrast between natural gold and the quartz sand), " standard " of placer salvaged and also is attended by almost all fine dispersion of gold and/or the loss of thin slice particulate.
For example, in Russian Amur area, extracting about 300 tons of gold from placer need abandon greater than 10
9m
3Dregs finish.Estimated as " IRGIREDMET research institute ", these dregs contain the unsegregated gold greater than 600 tons.In other words, (with respect to common extraction element) the artificial placer that a large amount of (deposits) occurred and in fact can't obtain replaces natural placer.
Usually, Jin this loss is equipped with the habitual salvaging and the flusher of shallow filling hurley log washer to cause by use.They have whole porous carpet veneer and hard can not moving platen (Karmazin V.I.Process andmachines for enrichment of minerals.-M:NEDRA Publishing House, 1974, pp115-188).
These hurley log washers and the design of collection carpet veneer and production are simple, and easy operating.But the hole of described carpet veneer is by very fast (acting on 1.5-2 hour) and filling very tightly of deposit.Therefore, the granule of gold and particularly fine dispersion and/or thin slice particulate skip over the bed of formation and flow of slurry and flow away together to enter and abandon the place, and the target product that the concentrate that is obtained contains very little.
In order to suppress the result that this is not expected, a lot of scientist's suggestions (so far) and Denver Nuggets person use comprise the steps, in fact the simplest method:
Regular interruption is sent to the ore pulp in the hurley log washer,
Withdraw the collection carpet veneer and
The concentrate that flushing is piled up from the carpet veneer hole.
Flow of slurry is interrupted frequent more, and this method reduces the productive rate of hurley log washer more.These interruptions can increase the cost of target product, even make weather allow to carry out the whole year placer mining, its extraction also is non-profit making.
Therefore, continue to attempt seek the bed that prevents in the hurley log washer fast with cross the method and apparatus that compresses.
Thereby the forced vibration that SU831180 discloses by the template glazing bar makes the loose method of bed.
Unfortunately, this method is when only in fact below layer remains unchanged, and makes that to be loaded in the upper strata chipped material of collecting in the carpet veneer hole loose.
Knownly hurley log washer is connected to vibrator as a whole stirs all concentrate (referring to op cit book ofV.N.Shokhin and A.G.Lopatin, pp.221 and 228), but this method relates to high power input and the damage of the critical piece of hurley log washer largely.And the vibration of hurley log washer does not have the effectively loose close concentrate (particularly being deposited on a time-out when deceiving heavy sand (black schlich) and gold) that bottom, carpet veneer hole produces of collecting.
Therefore, be used for promoting encirclement rock and/or native particulate (being preferably formed the gleanings dregs) must more be added with purpose from the fine dispersion of production and/or the loose of concentrate of thin slice target product separation of particles.
Hurley log washer according to RU2095147 provides the loose of relative autotelic concentrate with the collection carpet veneer, and it is the further hurley log washer and the carpet veneer of more approaching proposition structurally.
Known hurley log washer (specification of Fig. 1 and RU2095147) has:
(1) through-flow tank, its bottom is made by non-ferromagnetic body material at least, and when operation, it tilts with respect to horizontal line, and is connected to slurry source by the upper end, is connected to the device that is used to abandon the enrichment dregs by the lower end,
(2) porous is collected carpet veneer, and be arranged on the through-flow bottom of gullet, and below some holes, be equipped with the permanent magnetic body member at least,
The hard template of (3) one groups of shallow fillings that connect in the film mode, its each be connected to and be used for it along through-flow tank sidewall and reciprocating at least one drive unit of described carpet veneer, and have:
(3a) be arranged at least two files on the height collecting the carpet veneer top vertical fluctuation glazing bar and
(3b) be arranged between the described fluctuation glazing bar row and each rank rear of described glazing bar and the horizontal glazing bar in the space between the through-flow tank sidewall,
(4) be connected to described impulse generator and upper end based on pulse alternating current generator and its coil and be arranged on these that be equipped with described permanent magnetic body member and collect the solenoid of below, carpet veneer holes, in flow of slurry, produce the device of vertical vibration excitation,
Alternatively, known hurley log washer can be equipped with:
(5) hard template of filling of the deep fill that connects in the film mode in groups, its each comprise that (these glazing bars can be arranged in first hurley log washer part of collecting the carpet veneer top vertical fluctuation glazing bar, also can be arranged on the template top of each shallow filling of any other hurley log washer part, and be connected to suitable vertical reciprocating movement driving device), and/or
(6) horizontal glazing bar is rigidly fixed in the template framework, and is arranged between the fluctuation glazing bar row and between the sidewall of each last glazing bar and each through-flow tank, the height of the highly actual glazing bar that equals to fluctuate.
Known collection carpet veneer (Fig. 2 of RU2095147) has:
The elasticity porous upper layer, wherein each hole is formed by bottom and perisporium,
The elastic substrates layer, at least run location be fixed to this upper strata and
Straight permanent magnetic body unit is fixed with basalis, and is arranged in the below at least some holes on upper strata,
In described hurley log washer, the perisporium in the fluctuation glazing bar of vibration template and horizontal glazing bar and collection carpet veneer hole slows down flow of slurry, and the velocity field of on purpose twisting solia particle.Thereby, surrounding the slight grain of rock and/or soil and remove from each protuberance of fluctuation glazing bar, around flow of slurry, and the heavy mineral particulate remains near these protuberances or arrives these protuberances each protuberance of this fluctuation glazing bar at any passage.The vertical vibration of the described carpet veneer part under impulse solenoid and permanent magnet effect makes the concentrate that is deposited in the carpet veneer hole loose.As a result, the rearrangement of the repetition of all solids particulate in the velocity field promotes the enrichment of target product concentrate significantly.
But known hurley log washer can be effectively actual in the following cases through long-term research and development:
The initial granulometry of the encirclement rock that disperses and/or soil and valuable heavy mineral is formed similar substantially,
H/L in the ore pulp (being solid phase/liquid) is than preferably the scope 1/10 to 1/7 is stable, abandons the place because " high liquid " ore pulp is easy to bed is carried to, even deposit is washed away from the hole, and is loose but too much solid phase hinders deposit,
Actual mixture of for example not deceiving heavy sand.
But, even fine dispersion and/or thin slice particulate that such advantageous conditions can not satisfy most of Valuable Minerals move in the concentrate.This unfavorable result is produced by following reason:
The mixing of semisinusoidal fluctuation glazing bar, this in addition can not fix (even having horizontal glazing bar) in the short time, the rearrangement of the different particulates of density can obtain in each corner with respect to the flow of slurry of collecting the carpet veneer hole and
In fact all sedimental vertical vibrations, this promotes to catch the fine dispersion of valuable heavy mineral and/or thin slice particulate and these particulates are carried to by the flow of slurry in curved channel to abandon in the place.This growth of catching with the thickness of the bed on known collection carpet veneer increases.The setting of non-staple permanent magnet element below the carpet veneer hole and fluctuation glazing bar has also improved this and has caught.
Therefore, only, can reduce the loss of target product collecting the initial period that the carpet veneer hole is filled by concentrate.
Summary of the invention

Shape and position relation that these fluctuations and horizontal glazing bar reach the permanent magnetic element below collection carpet veneer hole make:
First, interrupt surrounding the slight grain and the rearrangement of heavy mineral particulate in the horizontal velocity field of rock and soil, this be arranged on ore pulp in the motion process around the semisinusoidal parts of every next fluctuation glazing bar (this interruption appear at the short time be arranged on described fluctuation glazing bar each to the straight insertion section between the semisinusoidal parts near)
The second, promote the vertical rearrangement of described particulate, the result in each interrupt procedure that described level is reset, the heavy mineral particle deposition, and slight agglomerate tabling is existing and
The 3rd, vibrate all in fact effectively and be created in concentrate in the hole, suspend with the slight grain that mainly will surround rock and/or soil, and make its major part break through horizontal glazing bar in flow of slurry, then to abandoning the place.
Occur in and collect in the carpet veneer hole and the result of these synchronizing processes of top is to have simplified the fine screening of valuable heavy mineral.Therefore, in each working cycles of hurley log washer, share and the extraction efficiency thereof of target product in concentrate increases substantially.Described advantage occurs under the following conditions:
The initial granulometry of rock and/or soil and valuable heavy mineral is on every side formed different substantially,
But the solid phase of initial ore pulp contain measuring amount black heavy sand and
The H/L ratio is less than 1/10 or greater than 1/7.

(these are formed by the edge of semisinusoidal parts 7, each the is straight part of insertion section 8 and the part of each horizontal glazing bar plate 9 with the zone of density bullets among Fig. 7) below promoting heavy particulate moved to the impact of the described plate 9 that is suspended on the horizontal glazing bar on the bar 10, flow of slurry is set in the hole 20 of collection carpet veneer 4 of magnetic element 5
In the vibration processes of the magnetic element 5 that is caused by solenoid 13, the thrust that acts on the porous layer 19 of collecting carpet veneer 4 is shaken the whole concentrate particulates that are deposited in the hole 20 effectively.
Therefore, the slight grain of rock that surrounds and/or soil floats to the surface of flow of slurry, and abandon from the otch inflow of upper lateral glazing bar 9, and the weight of valuable heavy mineral (even comprising fine dispersion and/or thin slice) particulate drops to the hole 20 of collecting carpet veneer 4 from horizontal glazing bar 9 surfaces, forms concentrate.
Because the laterally rotational angle of glazing bar plate 9 restriction at edge of the groove 12 in the straight insertion section 8 of glazing bar of being fluctuateed, weigh particulate from template 6 and collect gap between the perisporium 21 in hole 20 of carpet veneer 4 pass through be restricted.This advantage begins very important especially in the next time of each process.
Use is equipped with the collection carpet veneer 4 (Fig. 5) of clack valve 23 that the effective collection of the fine dispersion of valuable heavy mineral and/or thin slice particulate can be provided, and improves the share of target product in concentrate.
In fact, the energising each time of solenoid 13 vertically promotes permanent magnetic body member 5.Therefore, the lobe of valve 23 is slightly opened, and upwards promotes deposit, produces small whirlpool in fluid media (medium).Rock and/or native particulate that these small whirlpools at first will be deposited on the lighter encirclement in the hole 20 stir, and the rock of these lighter encirclements and/or native particulate flow through fibrage 24 usually, get back in the flow of slurry.Simultaneously, when the lobe of valve 23 moved down, fine dispersion and particularly laminar heavy mineral particulate were retained in the hole 20 by the fibrage 24 of deflection.
This advantageous effect is the most obvious from the extraction of artificial ore in sand form and demercuration process at gold, because:
Be deposited in golden particulate between the inclination lobe surface of the perisporium 21 in hole 20 and clack valve 23 and form high density group in the gap that is blocked between the lobe of opening, and
The atomic little particulate stream of liquid mercury forms big mobile drop together.
If ore pulp contains the black heavy sand particle mixture of ferromagnetism, then hurley log washer must use the magnetic separator (Fig. 6) that is placed on template 6 tops to operate.
When permanent magnetic element 5 promotes holes 20 when local ore pulp is splashed, the acquisition of the flow of slurry of ferromagnetic particle from passage and
In other moment of hurley log washer operation, the retroeflection (usually be attended by its accumulation horizontal glazing bar 9 above) of these particulates in flow of slurry.
In filler opening 20 backs:
Interrupt slurry stream by the hurley log washer ore deposit,
Haul out to the porous upper layer 19 of the described collection carpet veneer 4 of major general from through-flow tank 1 and
Later process can repeat above-mentioned steps.
