Refractory Gold Processes Mineral Processing & Metallurgy

Gold can be leached and extracted/recovered in several ways. Even if you gold is “refractory” in pyrite or arsenopyrite, you can still get much value from your ore/rock depending on the economics of capital and operating cost.

Gold mineral processing Hatch Ltd

Treatment of refractory gold ore (whole ore and flotation concentrates) has become more prominent since the 1980s, with many gold discoveries often including ores that are wholly or partially refractory. Refractory pre-treatment processes include pressure oxidation, biological oxidation and various forms of roasting. Design teams familiar with all three pretreatment processes can maximize a project's value.
