gold recovery with pyrometallurgy process

Gold extraction by chlorination using a pyrometallurgical

Mar 01, 2009· One of the most widely used chlorinating agents for gold recovery is calcium chloride. The non-ferrous and precious metals react with chlorine to form the corresponding chlorides, which are volatile at the temperature required for the process (1273–1473 K) (Panias and Neou-Syngouna, 1990, Deng and Li, 1987).

Gold refining by solvent extraction—the Minataur™ Process

Gold of either 99.99% or 99.999% purity can be produced from intermediate process products having a wide range of gold contents. The process comprises oxidative leaching of the solid feed, followed by selective solvent extraction of the gold from the leach liquor to reject impurities, and precipitation of high-purity gold powder.
