Definitions
- the invention relates to a method for continuous magnetic ore separation and / or treatment according to the preamble of claim 1. It should also be possible in particular a treatment of the substances used and a re-introduction into the process process. Furthermore, the invention also relates to the associated system for carrying out the method according to claim 11, in which in particular the method steps according to the invention are realized industrially with corresponding devices / devices.
- ore is understood to mean a metal-containing rock from which the metal-containing constituents are to be separated as valuable substances.
- the valuable substances are, in particular, sulfidic copper materials which are to be enriched, for example - but not exclusively - CU2S.
- the Cu-free rock surrounding the material grains is referred to as matrix rock or gangue, in the specialist world after milling the rock also as tailing or in the following briefly as sand.
- Magnetically assisted ore deposition methods have also been proposed, but these are discontinuous in the related art. Due to the discontinuous batch process, the yield and the associated efficiency are limited, which has an effect on the costs.
- drum separators for example, have only low mass throughputs and are therefore unsuitable for many of the mining processes used in mining.
- the object of the present invention is an overall process for the continuous magnetic ore deposition and in particular for the subsequent reprocessing indicate the substances used.
- a suitable system is to be created, which can be realized on a large scale in practice.
- the object is achieved by the measures of claim 1.
- An associated system with a suitable process arrangement is specified in claim 11. Further developments of the method and the associated device are the subject of the dependent claims.
- the invention thus relates to a continuous process for magnetic ore separation or preparation, including recycling of the most important substances used.
- the new process has a lower energy requirement and a higher extraction yield than the known processes and can in particular separate ore particles in a further particle size range than is possible according to the prior art.
- an inventive overall system can be largely composed of already available technical devices or facilities. In connection with the technical device for magnetization / demagnetization, in which the magnetized solid particle streams are separated from the respective liquid stream or the suspension, there are quite considerable improvements.
- FIG. 1 is a diagram with function boxes for the individual process steps with the individual material flows and
- FIG. 2 shows a concrete realization of the method according to FIG.
- the individual process sections are each entered in boxes with the associated chemical composition, the bold arrows indicating the respective sequence of the method sections and the dashed lines indicating the material flows from the recycled material with the respective arrows.
- magnetite FesC.sub.3
- magnetite in finely ground form is already hydrophobic, ie. it preferably binds to hydrophobic particles in aqueous solutions.
- the magnetite to be used is further treated in finely ground form with a surface modifying agent which makes the surfaces of the particles much more hydrophobic, i. water repellent, power. Hydrophobic particles agglomerate in aqueous suspension to minimize interfacial water.
- the magnetic properties of the magnetite are exploited by: can be separated from the nonmagnetic materials (gait) by means of defined magnetic fields or fields that can be activated by the magnetite with the value ore particles bound thereto.
- the following are examples of sulfidic copper minerals, the method can also be used for other sulfidic minerals such as molybdenum sulfide, zinc sulfide.
- Hydrophobing agent for other minerals the method described here can also be used for minerals of other chemical composition.
- Xanthat an agent known to selectively adsorb to and render hydrophobic the surfaces of sulphide copper minerals.
- the xanthate usually consists of a carbon chain with typically 5 to 12 carbon atoms and a functional headgroup that selectively binds to the copper mineral.
- a mixture of the input materials takes place in a first process step.
- the ore stream which consists of the ground rock (ore), water and - depending on the application - different chemicals, mixed with the required already hydrophobized magnetite and the other water repellents, especially the xanthate.
- the ore stream preferably has a solids content of about 40 to 70 percent by mass, which makes the stream pumpable and, according to FIG. 2, can be conducted by means of a pump 25 into a mixing vessel or stirred tank 26.
- the hydrophobizing agent is used for the hydrophobization of the valuable material contained in the ore stream.
- Magnetite is mixed together ("load process"), which requires a mixing device or agitator vessel 26, which must be designed to provide enough shear and residence time to allow the hydrophobization reaction and magnetite / ore particle assembly to take place ,
- a possible embodiment is a stirred tank 26, in which such a stirrer is used, which has high shear forces.
- the chemicals and the magnetite are metered in the vicinity of the stirrer.
- Such a stirrer must also be capable of ensuring not only local but also global mixing. It can alternatively be used an additional mixer, which also circulates the fluid. This results in large particles (agglomerates) consisting of hydrophobized resin and hydrophobized magnetite.
- the magnetite content and the value ore fraction are separated from one another (so-called "unload” process).
- Magnetite is additionally added to fresh, hydrophobized magnetite in order to supplement the substance loss which is unmatched in the overall process. This minimizes the need for relatively expensive magnetite when practicing the process, with the fresh magnetite being delivered in containers (e.g., "big bags") and metered in as needed.
- the chemicals are preferably added in dissolved form, because the metering and transport of liquids within the plant can be made more homogeneous, faster and more precise than the metering of solids.
- the box 6 includes the supply of diesel oil to the final product according to box 5 and a related mixture of both substances.
- the diesel oil on the one hand and the magnetite on the other hand are regenerated for further use.
- the magnetite, a part of the gait remaining in the crude concentrate, and diesel oil are returned to the entry step.
- FIG. 2 The mode of operation of the system for carrying out the method is illustrated in FIG. 2 on the basis of the sequence of all devices / devices.
- Reference numeral 20 here denotes the container ("big bag") for the magnetite with a metering device 21.
- the magnetite is mixed with water and recycled magnetite in a stirring device 22.
- the mixture passes through a metering pump 23 into a stirring device 26, wherein xanthat is supplied to the mixture via a second metering pump 24.
- the valuable substances in the form of the pulp are fed with ore via a further metering pump 25 to the stirring device 26.
- the pulp and the mixture with xanthate are used mixed in the stirring device 46.
- the stirring device 20 here denotes the container ("big bag") for the magnetite with a metering device 21.
- the magnetite is mixed with water and recycled magnetite in a stirring device 22.
- the mixture passes through a metering pump 23 into a stirring device 26, wherein x
- two magnetic separators 30, 40 are present, ie the process runs parallel in two process levels.
- the magnetic separators 30, 40 operate on the same physical principles. They each have a metering pump 27 and 39 assigned, which ensures the transport of the pulp.
- the aim of the magnetic separators 30 and 40 is to win a concentrate with a higher proportion of copper.
- the mixture of ore and magnetite is fed to the separation process, for which purpose a metering pump 27 is necessary.
- Tailing-stream represents a stream rich in water, and - depending on the application - either no longer contains valuable material and thus can be disposed of. If necessary, this stream still contains residual material and is therefore recycled for reworking.
- the separated stream contains the valuable substance as intermediate in comparatively high concentration
- the latter intermediate product stream is subsequently passed with the aid of at least one metering pump 31 to a drying step.
- the drying can, if necessary, be carried out in two steps.
- the first, indispensable step most of the water is extracted by means of a mechanical process, in particular by centrifugal forces. Depending on the process, this water can be returned to the process, resulting in a largely closed water cycle with little impact on the environment. However, the separated water can also be fed back directly into the pulp preparation.
- Another possible use is the admixture to the final product to make this transportable and, where appropriate, eliminate the effect of low residual moisture content.
- One possible embodiment for the first dewatering step is the use of the decanter unit 32 according to FIG. 2.
- This stream can, if necessary, for. B. be brought by means of a flexible screw conveyor 33 or a conveyor belt to a second drying step.
- This dryer can be operated eg by process steam or gas or oil burner. This creates steam that can be used elsewhere for preheating. The latter step may become superfluous depending on the application and process management. From the dryer comes a Feststoffström with a residual moisture content of less than 1%.
- This stream is cooled in a solid heat exchanger 36 and added, for example by means of a screw conveyor 37 to another stirred tank 38.
- the three process steps: coarse dehumidification-drying-heat dissipation are integrated in a single process unit, so that the number of apparatuses to be used in this step is reduced from three to one.
- the further chemicals in particular the non-polar liquid such as diesel, are added to the solids flow. It is necessary to choose chemicals that neutralize the hydrophobic bond between the recyclable material and the magnetite, which is ideally met by diesel.
- the diesel stream which is mixed in each case, contains the recycled diesel oil and a fresh portion of diesel oil, which is necessary to compensate for material losses in the overall process.
- the diesel content must be at least 40 percent by mass in order to make the mixture flowable and pumpable.
- the diesel-containing mixture is passed with the aid of at least one metering pump 39 to the subsequent separation step, in which the magnetite particles are separated from the ore.
- the "unload process” involves a further magnetic separation, which removes the magnetite from the material flow and then returns it to the "load process”. This results in two streams:
- the one stream contains the valuable material (ore) and is dehumidified with the help of the decanter 44.
- another thermal dryer can be used. Thereafter, this mass flow is given by means of conveyors 44 in a stirred tank 46, mixed with water and output as a final product "concentrate" via a pump 47.
- the magnetite stream is also dehumidified by means of a decanter 42.
- additional thermal drying steps may be added.
- Recovered diesel oil is in turn fed to the actual process, e.g. via the tank for diesel oil 50.
- the dry magnetite can be transported via a transport screw 43 to the stirring device 22. There, the recycled magnetite is mixed with fresh magnetite and water and returned to the material flow.
