The process mineralogy of gold: The classifi ion of ore The principal gold minerals that affect the processing of gold ores are native gold electrum Au-Ag tellurides aurostibite maldonite and auricupride. In addition submicroscopic solid solution gold principally in arsenopyrite and pyrite is also important. The main causes of refractory gold ores are submicroscopic gold the Au-Ag tellurides and very fine-grained goldand lt;10 µm
PDF Gold process mineralogy: Objectives techniques and Gold process mineralogy addresses all issues related to gold ore processing by the detailed study of an ore or a mill product. It is very important to establish an accurate process model for
Gold extraction - Wikipedia 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.
