Common Extraction Processes For Copper Ore Mining Pedia

nov 08, 2019 in-situ leaching process can be used to treat the residual ore of old mines or the unmined oxidized copper ore and lean copper ore. in-situ leaching process has better potential than other processes for those abandoned mines or uneconomical copper mines with other processes.the techniques for extraction of copper from oxidized ores are quite different from those employed for the sulfide ores. the oxidized ores, consisting of the silicates, carbonates and sulfates, are treated by several methods, all involving some form of leaching of the crushed ore with sulfuric acid to produce impure solutions of copper sulfate.hours ago the heap leaching technique was first used for precious metals recovery in 1969 at the cortez gold mine where it proved highly-efficient at improving recoveries from near-surface oxidized ore quoted operating costs based on current technology for leaching dumps and in-place ore, are between us$0.18 and us$0.22 per pound of cathode copper, which are competitive with the unit costs of smeltingrefining. heap leaching has the additional cost of mining and transporting to the leach pad.
