  • Heap leaching

    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

  • Leaching (metallurgy)

    Leaching is a process widely used in extractive metallurgy where ore is treated with chemicals to convert the valuable metals within into soluble salts. These can then be washed out and processed to give the pure metal; the material left over is commonly referred to as tailings.Compared to pyrometallurgy leaching is easier to perform, requires less energy and is potentially much less harmful
