摘要

"METHOD FOR EXTRACTION OF LEISURE OF MINES CONTAINING MINERALS AND CONCENTRATES AND METHOD FOR EXTRACTION OF CALCOCYTE ORES CONTAINING LOW PIRITS". It provides for a method for extracting bleach from copper / iron / sulfur ores and concentrates including leaching the mineral with an aqueous stream containing ferric ions and sulfuric acid in the presence of oxygen, wherein the aqueous stream includes a solution formed by the sulfate reaction. basic ferric with excess sulfuric acid; Integrated methods of formation and relixiviation of basic ferric sulfate are also described.
