  • 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

  • Tank leaching Wikipedia

    09-10-2007· Tank and vat leaching involves placing ore, usually after size reduction and classification, into large tanks or vats at ambient operating conditions containing a leaching solution and allowing the valuable material to leach from the ore into solution.

  • Vat Leaching of Finely Crushed Gold Ore

    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 distributors—the overflow in each case being slime or finer portion of the ore. As a rule, leaching is a simple process, involving a vat of well-mixed neutralized sand, ample contact with strong and weak

    29-07-2013· 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. The main disadvantage to vat leaching is higher capital and operating costs than
