Tank leaching is usually differentiated from vat leaching on the following factors: 1. 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;Wikipedia · Text under CC BY SA license
In the gold cyaniding process, leaching agitation tank is applied to leach and carbon absorb ore pulps whose fineness is 200 meshes and whose density is less than 45%. Under similar circumstance, it is also applied to agitation and leaching in metallurgy, chemical and light industry.
A cyanide leaching circuit usually consists of large agitated tanks for mixing mineral slurry with cyanide in order to extract gold. Typically, the slurry consists of 30 40% solids by weight with the solid particles being less than 100 microns in size. Air or oxygen is often bubbled through the slurry to improve the leaching reaction.

The first tank of each train is purely a leach tank , the remaining six are leach and adsorption tanks. Each tank has an effective volume of 761m3 each, and operate at a leach density of 50% solids, giving a residence time of approximately 4 hrs leach and 22 hours CIL.
