Gold Ore Processing Methods

Flotation is one of the most widely used methods for gold ore processing. Through this method, gold can not only be enriched into sulfide mineral concentrate to the maximum extent, but also waste tailings, with low beneficiation cost. Cyanidation It refers to the process of extracting gold with cyanide as leaching solution.
