Potential pre-treatment and processing routes for recovery of …
Gold can be found in complex sulfide minerals in particular, pyrite and arsenopyrite (Asamoah et al, 2018). In refractory gold ores, the gold is highly encapsulated in the sulfide matrix and pre-treatment is an important process to recover gold from the sulfide minerals. The sulfide minerals interfere with recovery of gold thus it is imperative
