  • Bioleaching of copper ore flotation concentrates

    01/01/2003· During the bioleach–biooxidation process, the copper is released into the solution and the solid is sent to a cyanidation process for gold recovery. Bacterial leaching of copper sulfide flotation concentrate is a complex process. Bioleaching of copper flotation concentrate has been investigated by Rivera-Santillan et al. (1999). Compared with other copper sulfide concentrates the Polish

    The cyanide acts by reacting with copper in solution, If the plant includes cyanidation to recover Au from flotation concentrates and/or tails, the use of cyanide as a depressant can be accommodated as these plants include cyanide destruction. If water from the cyanidation plant is to be recycled to the flotation section then cyanide in solution needs to be controlled. As discussed in

    Concentrates are the raw material for all copper smelters, which by processing it obtain an impure form of metallic copper, anode or blister copper, which is later used to produce high purity refined copper. The production of concentrates implies the crushing and later milling of the ore down to a particle size allows releasing copper by flotation. The concentrates from different regions have

About 80% of the uranium minerals remain in the tailings from the flotation cells, from which they are recovered by acid leaching as in a normal uranium mill. The copper concentrate is also processed through an acid leach to recover much of the other 20% of the uranium.

    Cobalt is recovered by flotation into a concentrate wherefrom it is leached by pressure oxidation followed by solution purification (involving copper solvent extraction and iron removal), ion exchange, precipitation and electrowinning. The pressure oxidation occurs with selective rejection of arsenic and iron allowing environmentally acceptable tailings disposal as ferric arsenate. The process
