The development of regrind–flotation pre-treatment of the CIL

2014.5.1  1. Introduction. In porphyry/skarn copper–gold flotation plants gold recovery is often well below copper recovery [1].With liberated and copper-associated gold readily recovered in the flotation stage, this recovery difference is often due in part to operating strategies that require rejection of gold-bearing iron sulphide gangue minerals in order to

Suzdal • Nordgold

As the gold is encapsulated in sulfide minerals such as pyrite and arsenopyrite, the gold is prevented from being leached by cyanide. The BIOX process destroys sulfide minerals and exposes the gold for subsequent cyanidation, thereby increasing the achievable gold recovery. Suzdal’s BIOX circuit commenced operation in 2005 with a plant ...
