Leaching (metallurgy)
In heap leaching, the mined ore is crushed to size, usually below 20–25 mm, and heaps are scientifically prepared and engineered on prepared bottom pads. In vat leaching, more finely crushed ore (1–10 mm) is placed in a large basin (vat) flooded with leachant solution and left to react with time.

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 ...
