It usually operates at an elevated temperature to increase the solubility of the solute in the solvent. • Feed to a leaching system typically is solid, consisting of basically insoluble carrier material and a (usually desirable) soluble compound.Tank leaching - WikipediaTank 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;

Small Scale Modular Gold Batch Cyanide Leaching Plant ...

Then the barren solution is filled to continue leaching and decantation. The leaching efficiency is increased much because the gold bearing solution is discharged out of the leaching tank in time and the tank is filled by barren solution. Because of batch operation, a battery of tanks work by turns.
