Thiosulphate Leaching Mining Sgs

Thiosulphate Leaching Mining Sgs

This process results in recoveries that are close to those generated by cyanide leaching in many cases In recovery operations that are affected by “preg robbing” ores it can yield substantially better recovery than cyanide Thiosulfate leaching is particularly well suited to state of the art resin in pulp (RIP) gold recovery technologies
