Leaching Manganese

Second, the leaching rate of manganese is affected by gangue minerals present in the ore. Calcium for instance, is readily solubilized by SO2 solutions which diminishes the opportunity for manganese dissolution. This was evidenced by the results of leaching tests on two ores with similar manganese and iron contents, but different calcium contents.

Gold extraction

A "refractory" gold ore is an ore that has ultra fine gold particles disseminated throughout its gold occluded minerals. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. These refractory ores require pre treatment in order for cyanidation to be effective in recovery of the gold.
