Copper Sulfide Mining Earthworks
Oxide copper ore, mixed oxide-sulphide ores and low-grade copper sulphide ore, which, for economic reasons, cannot be enriched by flotation, may be processed by leaching methods. Agents for leaching copper can be acid, base, or salt solutions. Of all of these agents, sulphuric acid has been given the.
Jun 30, 2014 A scoping study, completed in early 2012, confirmed the potential to mine and process mixed sulphide and oxide ores at Lubembe. The Mineral Resource of 93 million tons at a grade of 1.9 copper will be mined by open pit methods, at a rate of 3.6Mtpa run of mine ore.
