Vat Leaching. Vat leaching is similar to heap leaching except that the heap is smaller, located in a vat and immersed in liquid solvent so as to soak the ore to extract the minerals. This process typically takes 9 to 20 days and yields between 65% and 85%—depending upon particle size and residency times.

Tank leaching - Infogalactic: the planetary knowledge core

Tank vs. vat leaching 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;
