  • 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
