Tank leaching

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 ,...

Gold processing

With ores of higher gold content (ie, greater than 20 grams of gold per ton of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent for several hours in large tanks equipped with agitators For extracting gold from low-grade ores, heap leaching is practiced...

Gold Cyanidation

Process Cyanide can be used to extract gold, either in a controlled mill environment, or more crudely on rock piles in the open Cyanide "vat leaching" mixes finely crushed ore with a cyanide salt in water The cyanide binds to the gold ions, and makes them soluble in water, thereby allowing separation from the rock...
