Tank bioleaching of copper from combined flotation
Highlights In this research, copper bioleaching from combined flotation concentrate and smelter dust was investigated. A couple of bioleaching methods were investigated in this work: fractional and nonfractional dustaddition strategies. The highest copper extraction obtained with the fractional dustaddition was up to 94%. The extraction using the nonfractional method leveled off at

It is worth noting that the main phase of the flotation concentrate was chalcopyrite as a primary sulphide, but the smelter dust mainly contained secondary copper sulphides such as Cu 2 S, CuS, and Cu 5 FeS 4.Under optimum conditions, copper dissolution from the combined flotation concentrate and smelter dust as an environmental hazard

magnitude increase in energy utilization in the collection zone over tank flotation has the ability to recover such ultra fines. This paper details two separate site based pilot plant investigations into the ultra fine losses occurring into tailings by tank flotation and the ability of Imhoflot to recover these ultra fines.
