Submerged Vat Leaching VS Trickle Leaching
A typical submerged vat leaching plant is described as follows: Ore is crushed to optimum size for copper extraction using two or three-stage crushing. This size will typically be from ¾ inch to 3/8-inch top size. The crushed ore is then bedded in a vat with special care to prevent segregation of the coarse and fine fractions.
