Copper Extraction From Chalcopyrite && new projects

Sustainable mining solving the problem of chalcopyrite ,chalcopyrite ore forms the significant fraction of copper deposits in the earth crust. however, it is also the most difficult to treat using conventional ferric leaching methods. smelting and electro-refining are currently the methods used in treating chalcopyrite concentrate obtained from froth flotation.

Sustainable Mining Solving The Problem Of Chalcopyrite

chalcopyrite ore forms the significant fraction of copper deposits in the earth crust. however, it is also the most difficult to treat using conventional ferric leaching methods. smelting and electro-refining are currently the methods used in treating chalcopyrite concentrate obtained from froth flotation.stage roasting At this stage of the process, the chemical reactions begin. they convert the copper minerals into copper metal. We can illustrate the types of process using the example of chalcopyrite cufes 2.from the formula, it is clear that iron and sulfur have to be removed in order to produce copper.the major steps in the extraction of copper are. copper in chalcopyrite is reduced to copper sulphide. just like in blast furnaces, calcium carbonate is added as a flux to create the slag. iron in chalcopyrite is removed as iron silicate slag. most of the sulphur in chalcopyrite turns into sulphur dioxide
