  • Heap leaching

    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

    Vat leaching is carried out in vats ranging in capacity from 30 to 1200 tons. Sand for leaching is separated from slime in cones, V boxes, classifiers, and in collecting vats filled by distributorsthe overflow in each case being slime or finer portion of the ore.

    Vat leaching also contains an environmental advantage over heap leaching. The footprint of a vat plant is much smaller than that of a dedicated heap leach operation, even when considering disposal of vat tailings. A smaller treatment area also leads to plant simplicity and reduced cost of material transport.
