The Recovery of Copper in Sulphide Ores by Roasting, Leaching, and ...

Sulphide ores of copper are insoluble in dilute sulphuric acid leaching solutions, but a very high extraction can be obtained if the copper ore is in the oxidized condition. The problem is to convert the sulphide into the oxide form. This can be done by giving the sulphide ore an oxidizing-sulphatizing roast. Copper sulphate is soluble in water, so acid will be saved in the leaching process if ...

The extraction process is quite similar between lead and copper sulfide ores. The lead ore is ground down into a dust. Once crushed, the ore undergoes a floatation process that allows the lead to float to the top of the solution and be skimmed off. The lead mixture is then dried and heated to over 2500 oF. This removes some impurities like sulfur.
