Autoclave Circuit & Gold
Process air is also injected into the acidulation tanks to aid in carbon dioxide removal. Carbonate levels are typically reduced to <2% in the acidulation tanks. As a rule of thumb, about 1% sulfide sulfur (S ) in the autoclave feed destroys 0.9% CO3 and typically the autoclave feed ranges from 2.0% to 2.5% S2-.
Processing centres in artisanal gold mining
The processing centres use a crude grind to liberate fine gold particles before processing, negatively affecting gold recovery. They use rudimentary methods to concentrate the gold, or they simply amalgamate the whole ore using copper-amalgamating plates ( Fig. 1 ), or they grind the ore with mercury in small ball mills.
