  • Bacterial heap leaching Practice in Zijinshan copper mine

    Accumulation of acid and ferric ions is a big challenge to the heap leachingSXEW for the Zijinshan copper ore. The results of the pilot plant show that the process of heap leachingSXEW works well at Zijinshan copper mine, but water balance, acid balance and iron balance remain challenges to the commercial plant.

  • Heap bioleaching of chalcopyrite A review ScienceDirect

    Heap leaching deals with the newly mined/run off the mine (ROM) materials (intermediate grade oxides and secondary sulfides) deposited in the form of a heap on an impervious natural surface or a synthetically prepared pad leached with circulation, percolation, and irrigation of the leaching medium. Primary sulfides like chalcopyrite are

    SummaryExamples of Current Industrial Bioleaching OperationsBackgroundChemistry of BioleachingMicrobiology of BioleachingLeaching MethodCostsResearchConclusionsBioleaching is the extraction of a metal from sulfide ores or concentrates using materials found native to the environment; namely, water, air and microorganisms. In other words, bioleaching is the commercialization of the ability of certain bacteria and archaea, found in nature, to catalyze the oxidation of sulfide minerals. It is the leaching of sulfide minerals that distinguishes bioleaching from conventional acid leaching wherein only oxidized minerals are leached.An associated process isLive Chat

  • Heap Leaching Mining Fundamentals

    Heap leaching is an industrial mining process of separating precious metals, copper and other minerals from ores. It involves a series of chemical processes through which the mineral ores are piled in the form of a heap and a leach solution is spread over the ore surface to leach metal from the heap.
