Vat Leaching of Finely Crushed Gold Ore

Jul 13, 2016  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 ...

4 Factors Affecting Gold VAT Leaching Process

Jun 05, 2020  Gold vat leaching process is currently widely used in small-scale gold mines, because of a series of advantages including high recovery rate, strong adaptability to ore, low cost and simple process. The basic principle is first to leach the gold from the ore with cyanide solution containing oxygen, and then to extract the gold from the leaching solution with zinc powder or zinc wire.
