small gold processing plant indonesia Solutions Just Right For You

The non-flammable and water-soluble inorganic compound dissolves fine gold out of ores into a solution, this alternative reagent can also be recovered after processing and reused. "This enables miners of all sizes, from small-scale and artisanal miners through to larger-scale miners, to tap the Earth's riches in a more sustainable way," says Mr McCulloch. Artisanal and small-scale production supply accounts for 80% of global sapphire, 20% of gold mining and up to 20% of diamond mining. It is widespread in developing countries in Africa, Asia, Oceania, and Central and South America. Though the informal nature and on the whole un-mechanized operation generally results in low productivity, the sector represents an important livelihood and income
