Modular Plants: Gold Processing
1 to 100 tonnes per hour (tph). Should higher capacities be required, units can be duplicated adjacent to each other to increase throughput. During the design phase, potential processing routes are identified and evaluated to optimise gold beneficiation of the particular gold bearing ore. Modular plants offer a complete solution

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.
