Stages of Hydrometallurgical Processes

Stages of Hydrometallurgical Processes

Vat Leaching :The ore meant to be leached is loaded into vats that are typically made of concrete. When leaching has been completed, the residual solids are dugout of the vat and replaced by a fresh batch of ore.[4] 10 Process Stages Suitable for porous and sandy materials [4] commonly used to extract gold and silver from ore [11]

Application Note Cyanide Leach Process pH

Cyanide Leach Process - pH Mining: Gold Processing While there are many different processes to remove gold from its encapsulating ore, cyanide leaching (cyanidation) is perhaps the most common and well known. A cyanide solution (NaCN or KCN) is elevated to a high pH level ( 10.5pH) so that free cyanide (CN-) will dissolve the gold in the ore.
