A ferric sulphate leach step to extract copper from chalcocite (Cu 2S) in the sulphide ore or concentrate. This leach enables use of simple atmospheric reactors, gives good copper extraction, and allows regeneration of the leachate using bacteria or pressure oxidation of the liquor.
How is copper extracted by hydrometallurgy?
Hydrometallurgical copper recovery can be conveniently considered in two stages: the leaching stage, in which the various forms of copper in the ore are placed into an aqueous solution, and the recovery stage, where dissolved copper is recovered as solid, nearly pure copper metal ready for fabrication or final smelting ...
What is the process of extracting copper?
Copper mining is usually performed using open-pit mining, in which a series of stepped benches are dug deeper and deeper into the earth over time. To remove the ore, boring machinery is used to drill holes into the hard rock, and explosives are inserted into the drill holes to blast and break the rock.
