PRESSURE OXIDATION OF REFRACTORY GOLD ORES: THE METATES GOLD

Pressure Oxidation Pressure oxidation is employed to liberate gold and silver in refractory sulfide concentrates often and ores. The main pressure oxidation products from iron sulfide minerals are sulfuric acid (and metal sulfates) and hematite. Depending on the conditions within the autoclave, acid containing iron compounds can be formed.

Gold recovery from refractory gold concentrates by

Pressure oxidation technology for the treatment of refractory gold concentrates has been deployed in some countries. Shuiyindong gold deposit is one of the Carlin-type deposits which is a typical difficult-to-treat gold deposit, located in Guizhou province in western China. It was the first application of acid pressure oxidation in China.
