Used Copper Leaching Plant Price
Most ores occur as mineral compounds that are insoluble in water; leaching involves chemical reactions that convert copper into a water-soluble form followed by dissolution. The leaching reagent used by each operation is dependent on the mineralogical composition of the ore material. Several types of reagents are used to produce these chemical reactions, including acids and bacterium.
Acid leaching of ores and concentrates is the most common method of hydrometallurgical extraction. Its use is confined to acid-soluble, oxide-type ores that are not associated with acid-consuming rock types containing high concentrations of calcite.
Copper Leaching Plant
Leaching is a method where valuable minerals are selectively dissolved from a material by a lixiviant, normally aqueous solution, resulting in a rich solution. Afterwards, the valuable mineral needs to be recovered, for instance by precipitation. The valuable mineral or compound can appear in the material being leached in at least three physical forms: as free particle, as multiphase particle in which the valuable mineral is exposed on at least one side to the lixiviant, and as inaccessible material surrounded by gangue material.
There are several techniques of leaching. These can be grouped into fixed bed procedures, such as percolation leaching, heap leaching, and in-situ leaching, as well as leaching in a pulp in movement such as in agitation leaching (tank leaching) and pressure leaching.
Copper Beneficiation Equipment
Copper beneficiation is the process of obtaining copper from its ores. It consists of a series of chemical, physical, and electrochemical processes. As in all mining operations, the ore must usually be beneficiated). To do this, the ore is crushed then it must be roasted to convert sulfides to oxides, which are smelted to produce matte. Finally, it undergoes various refining processes, the final one being electrolysis.
