  • In situ leach

    In situ leaching, also called in situ recovery or solution mining, is a mining process used to recover minerals such as copper and uranium through boreholes drilled into a deposit, in situ. In situ leach works by artificially dissolving minerals occurring naturally in a solid state. For recovery of material occurring naturally in solution, see Brine mining. The process initially involves the drilling of holes into

  • Producing Copper Nature's Way Bioleaching

    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
  • Uranium mining

    In situ leaching (ISL), also known as solution mining, or in situ recovery (ISR) in North America, involves leaving the ore where it is in the ground, and recovering the minerals from it by dissolving them and pumping the pregnant solution to the surface where the minerals can be recovered.

  • TENORM Copper Mining and Production Wastes Radiation

    Mining and Processing MethodsWaste GenerationDisposal and ReuseEPA and The StatesOres that contain copper in the U.S. are typically mined in large, open pits. Copper processing facilities are usually located near mining or extraction sites. Significant waste volumes are associated with copper production. Mine wastes may contain radionuclides due to their natural presence in ores and can be a source of TENORM.Uranium, which may be co located with copper ore, may also be recovered as a side stream, if economical. However, in the United States this is not a general practice.Live Chat
