Small Portable Copper Ore Concentration Plant
Most mined copper ore is low grade and bound up within valuable ore minerals, with unwanted rock or gangue minerals. The main objective in the metallurgical treatment of any ore is the separation of ore minerals from gangue minerals within the rock.
The first stage in copper concentration opeartion circuit is crushing and grinding, where the rock is crushed to produce small particles consisting of individual mineral phases. These particles are then separated to remove gangue, thereafter followed by a process of physical liberation of the ore minerals from the rock. The process of liberation of copper ores depends upon whether they are oxide or sulfide ores. The technique applied for copper concentration includes gravity concentration, flotation, leaching, refining etc.
Copper Ore Concentration Plant
There are many different types of techniques and equipment involved in copper concentration process, such as crushing; grinding; washing; filtration; sorting; sizing; gravity concentration; magnetic separation; flotation; and agglomeration etc. SBM has been specialized in mining industry for long history, we developed comprehensive sets of copper concentration and beneficiation equipment for sale. The newly developed small portable copper ore concentration plant is excellent for small scale copper processing project.
Gravity concentration is a method of separating minerals of different density by the force of gravity or by other forces, such as centrifugal force or the resistance to movement offered by a viscous fluid, such as water or air. The motion of a particle in a fluid is dependent not only on its specific gravity, but also on its size and shape. Advanced gravity concentration has proven itself to be an alternative to flotation and leaching, since, among other reasons, no reagents are required.
Froth flotation is the standard method of concentration used in the copper industry. The copper ore is crushed and ground to a size such that an acceptably high degree of liberation has occurred between the copper sulfide ore minerals and the gangue minerals. The ore is then wet, suspended in a slurry, and mixed with xanthates or other reagents, which render the sulfide particles hydrophobic.
The simplest froth flotation operation is the separation of sulfide minerals from gangue minerals (such as limestone or quartz). The separation of different types of sulfide minerals, such as chalcopyrite, from pyrite is more complex, because the surfaces of the minerals have to be modified so that the reagents attach only to the mineral to be floated.
