The key issues in the conceptualisation and testing of treatment options for gold and base metals mineral processing projects are discussed. A prerequisite of this process is the need for close ... of sampling and testwork required. A simple, near-surface, free-milling gold ore may require only a small amount of sampling and testwork. A complex ...

A Pretreatment of Refractory Gold Ores Containing Sulfide Minerals …

The use of thiosulfate to extract gold from refractory ores is promising because of its non-toxicity and high selectivity. Sulfide minerals (i.e., pyrite, arsenopyrite, chalcopyrite), major gold carriers in refractory gold ores, however, hinder gold extraction due to the high consumption of a lixiviant. In this study, a new method to improve gold extraction from sulfide bearing gold …
