| description | The invention relates to a method of preparing high pure copper from the leachate of primary sulfide ore bacteria, including: it leaches the primary sulfide ores and its mixture by using the mixture of middle and mesophilic bacterias. It filters and extracts the bacterial leaching solution, and conducts thin-layer wash-condensate, coalescence phase, and back-extraction electrowinning for the organic phase load. The invention uses hybrid strains of bacteria and sub-culture techniques to enhance the synergy of the bacterial leaching role and the minerals leaching rate, uses gelatin and other additives without sulfur element to reduce the sulfur impurities. |
