    Hydrometallurgical process is the process of extracting copper from pregnant liquid by leaching copper from ore or concentrate with solvent. The main processes include leaching, solvent extraction, electrodeposition and so on. At present, leaching methods mainly include heap leaching, underground leaching, stirring leaching and biological leaching.

  • Heap leaching - Wikipedia

    Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ...

    Copper processing - Copper processing - Ores: Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature. Occasionally copper is still found in its native form, but more frequently it is mixed with other minerals, some of which may have value themselves.

    17-08-2020· Copper was discovered and first used during the Neolithic Period, or New Stone Age. Though the exact time of this discovery will probably never be known, it is believed to have been about 8000 bce. Copper is found in the free metallic state in nature; this native copper is the material that humans employed as a substitute for stone.

    Copper hydrometallurgy is a branch of metallurgy method to extract copper directly from those difficult-to-concentrate copper oxide ore. Traditional copper hydrometallurgy process typically consists of atmospheric leaching, solvent extraction (SX) and electro-winning (EW). It can produce either copper cathode or copper sulphate crystal.

    Once solvent extraction proved to be a cost-effective way to purify and concentrate copper from leach liquors, copper ore leaching processing began to regard leaching as a much more important source of copper. Two early advances in leaching include the distribution of large drops of leach solution over the ore at Baghdad in 197019 and the use of drip irrigation by Johnson Camp in 197620.

  • Copper Mining and Production Processes Explained

    Leaching offers an alternative to copper mining. First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SX-EW (solvent extraction/electrowinning).
