text: Chalcopyrite, CuFeS 2 , usually in the form of a concentrate containing about 70 to 90 percent of CuFeS 2 , has been treated by a variety of prior art processes to decompose it to simple copper sulfides such as CuS or Cu 2 S. Copper can then be recovered from these sulfides by means of conventional hydrometallurgical processes such as leaching with an acid, e.g., hydrochloric or sulfuric, solution at low pressure and temperatures at or below 110° C. Metallic copper can then be recovered from the solution by electrolysis, cementation, etc.
