Gold Ore Tank Leaching vs. vat leaching Pineer Mining

1 天前  Factors. Tank leaching is usually differentiated from vat leaching on the following factors: In tank leaching the material is ground sufficiently fine to form a slurry or pulp, which can flow under gravity or when pumped. In vat leaching typically a coarser material is placed in the vat for leaching, this reduces the cost of size reduction;
