Definitions
- the invention relates to a method for separating Werterzpumblen, in particular CU 2 S from agglomerates containing Werterzp motherboard and attached to these magnetizable particles, in particular Fe3 ⁇ D 4 , as part of a process for obtaining value ore from raw ore, within which agglomerates rate the ore and the magnetizable particles are linked by organic molecular chains.
- Suitable magnetizable particles are referred to hereinafter by way of example and is representative as the "Fe 3 O 4", thus, other suitable compounds or alloys are meant.
- Suitable ores are named by way of example and is representative of Cu 2 S in the following, thus, other ores are meant.
- the ore In order to separate the copper sulphide from the ore, the ore is first finely ground until it is virtually powdery. Subsequently, magnetization (Fe 3 ⁇ D 4 ) and other chemical additives containing agents which cause hydrophobization of the CU 2 S and Fe 3 O 4 are added to the magnetic deposit of CU 2 S. This hydrophobization arises as a result of the longer-chain organic molecular chains contained in the additives, which accumulate selectively on the CU 2 S and the Fe 3 ⁇ 4 . These are thus surrounded by a water-repellent shell.
- the size of the CU 2 S and Fe 3 ⁇ 4 particles are in the ⁇ m range, they tend to agglomerate, that is, larger, cluster-like agglomerates of one or more Cu 2 S particles and a plurality of Fe 3 ⁇ 4 particles, the Cu 2 S particles being bonded to the Fe 3 ⁇ 4 particles via the organic molecular chains.
- the CU 2 S particles are almost completely enveloped by Fe 3 ⁇ 4 particles, and the organic molecular chains sit between the Fe 3 ⁇ D 4 and the Cu 2 S particles.
- the invention is thus based on the problem of specifying a method which allows a better separation of the associated by the hydrophobization Werterzteilchen and magnetizable particles.
- a method according to the invention provides that the agglomerates simultaneously experience both an input of mechanical energy to break up the compounds via the molecular chains and an input of thermal energy to decompose the molecular chains.
- the Agglo- meratmaterial is usually dried, so that for the implementation tion of the inventive method quasi dry powder is present.
- a mechanical and a thermal process are provided according to the invention, to which the particles are subjected simultaneously.
- the agglomerates are treated mechanically in order to mechanically break up these chain compounds by the action of mechanical energy on the particles or the complete agglomerates connected via the molecular chains.
- the agglomerate or powder material is heated, with the result that the molecular chains, insofar as they are exposed as a result of the mechanical treatment, are thermally decomposed or destroyed, and thus incinerated and consequently can no longer lead to a particle compound.
- the molecular chains insofar as they are exposed as a result of the mechanical treatment, are thermally decomposed or destroyed, and thus incinerated and consequently can no longer lead to a particle compound.
- CU2S molecular chain-free Werterz, so for example CU2S, and magnetizable particles, eg. B. Fe3 ⁇ 4 , before. Both particles can be separated by downstream process technology, which will be discussed below.
- the agglomerate material is expediently ground, for which purpose the agglomerates, in the dried state, together with grinding elements, in particular grinding balls, are ground into a grinder which can be used for parallel feeding. drove thermal energy is heated, be given. So there is a heatable grinder is used, which offers the opportunity to be able to supply the mechanical and thermal energy simultaneously.
- the grinder itself is a separator, in particular a sieve, for separating the grinding elements of the now free particles, for. B. CU2S and Fe3 ⁇ 4 , downstream.
- This may, for example, be a vibrating screen onto which the treated material leaving the rotary kiln and the grinding balls fall.
- the fine Cu 2 and Fe 3 O 4 falls through the vibrating screen, while the balls remain above the vibrating screen, collected by this and turn the rotary kiln together with not treated Cu2S / Fe 3 O 4 - agglomerates are fed.
- the separated ore particles and magnetisable particles can now be treated with any downstream process technology in order to separate the substances from one another.
- the powder containing the two materials can be guided by means of a conveyor belt into a magnetic field, via which z. B. the ferromagnetic F ⁇ 3 ⁇ 4 is separated from the CU2S.
- this "dry" separation a wet separation by dissolving the powder in the water and pass through a tubular reactor with mag- netic separation.
- the Fe 3 O 4 so The magnetite, be recovered at least 98% and used as an aggregate for the ground ore powder standing at the beginning of the process.
- the invention further relates to an apparatus for carrying out the method.
- This comprises a heatable grinder into which agglomerates consisting of ore and magnetizable particles connected thereto via organic molecular chains, in particular Fe 3 U 4 , are introduced, together with grinding elements, in which the agglomerates are introduced by introducing mechanical energy through the grinding elements broken up and decomposed by entry of thermal energy into the material to be ground in the grinder, the molecular chains, and a downstream of the grinder device for separating the grinding elements of the separated Werterzpumblen and magnetisable particles.
- the grinder is suitably a rotary kiln, which allows continuous operation.
- the separating device which is connected downstream of the rotary kiln, is expediently a screen, preferably a vibrating screen.
- the device according to the invention further comprises a magnetic separation device connected downstream of the separating device for separating the magnetisable particles from the Cu 2 S.
- Fig. 1 is a schematic representation of a Cu 2 S and Fe3Ü4 contained agglomerate, which are bound via organic molecular chains
- Fig. 2 is a schematic diagram of an apparatus according to the invention for carrying out the method.
- Fig. 1 shows in the form of a schematic representation of an agglomerate 1, consisting of in the example shown four Cu 2 S particles 2 and a plurality of these surrounding ferromagnetic oxide components, here Fe 3 ⁇ 4 particles 3, the sake of clarity here drawn much smaller are.
- the Cu 2 S particles 2 and the Fe 3 ⁇ 4 particles 3 are interconnected by longer-chain organic molecular chains 4.
- This organic chain material was the finely ground at the beginning of the recovery process, prepurified ore together with the powdered Fe 3 Ü 4 added to hydrophobize both the Cu 2 S contained in the ground ore, which is non-magnetic, and the ferromagnetic Fe3Ü4 and an addition of Fe 3 ⁇ 4 -Particles 3 on the Cu 2 S particles 2 to enable so that these agglomerates can be separated magnetically from the other ground ore material. Now it is necessary to break up these agglomerates again and that
- agglomerates 1 after drying together with grinding elements, here in the form of grinding balls 5, placed in a grinder 6 here in the form of a rotary kiln 7.
- the rotary kiln 7 rotates continuously about its longitudinal axis, as shown by the arrow P.
- a heater 8 is provided, which here for example via Fuel gas is fired, that is, it is possible to strongly heat the interior of the rotary kiln 7.
- the grinding balls 5 now grind the agglomerates 1, thus breaking the chain connection by introducing mechanical energy during the time in which the grinding balls 5 and the particles 1 are in the rotary kiln 7.
- the exposed molecular chains 4 are thermally decomposed in parallel, ie burned.
- the rotary kiln 7 permits continuous working, after it can be continuously charged with new particulate material to be processed together with grinding balls, while at the end of the kiln the now separated particles together with the grinding balls can be drawn off continuously and sent for further use.
