Gold Refining Process Mineral Processing & Metallurgy

01/04/2016 The gold occurring in the alluvium is not refined by any of Nature’s processes—but the accompanying minerals or metals are either oxidised or removed hence, in the recovery of gold from reefs impurities are often collected and introduced, thus making it of lower value than the corresponding alluvial gold

Gold Extraction & Recovery Processes

29/02/2016 Cyanide solution percolates through the heap leaching the gold and silver and is collected on the pregnant solution pad. The ore is crushed to a size that will give good liberation of gold minerals. In most operations with this crushing stage, the ore is crushed until two-three inch. A finer size can be considered if the ore needs fine liberation. The leach cycle is normally from 20 to 30 days

Gold Refining From Gold Ore to Doré World Gold Council

When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent in large tanks equipped with agitators.
