gold processing for artisanal miners

Strategies for sustainable gold processing in the ...

any plant for processing or extraction of gold or gold bullion that is not operated exclusively for the benefit of an operator who mines the gold. In this set up, artisanal and small scale miners bring ores for milling and recovery of free gold for a fee and leave gravity concentration tailings for the mill

ARTISANAL AND SMALL-SCALE MINING

ASM often exploits deposits of 3T minerals (tin, tantalum, tungsten), gold, cobalt, or gemstones, which in many regions of the world have been linked to financing armed conflicts and criminal networks. In rural and remote areas, ASM is often the only employment alternative for poor, un - educated people besides traditional subsistence farming.
