  • Tank leaching

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