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 ...
