Beschreibung
Zusammenfassung:	The invention relates to a combined technology for treating copper sulfide ore. The combined technology comprises a biological heap leaching technology, a stirring and leaching technology, and a flotation and fire-process technology; an ore body is divided into three types according to the following technology: firstly, carrying out crushing, ore grinding and flotation on deep-layer ore to obtaincopper concentrate and floated tailings; carrying out fire-process smelting on the copper concentrate to obtain crude copper and sulfuric acid; carrying out electrolytic refining on the crude copper to obtain cathode copper, copper sulfate and anode mud; recycling rare bulk noble metal from the anode mud; then stirring and leaching by utilizing sulfuric acid generated by a fire process, and carrying out crushing, ore grinding, acid leaching, biological stirring and leaching, extraction and electrodeposition on shallow-layer ore to obtain the cathode copper; carrying out the biological stirringand leaching to obtain a
