Gold Ore - an overview ScienceDirect Topics

Gold ores are classified “free-milling” and “refractory” based on their response to cyanide dissolution. Bioprocessing can be used to treat refractory gold-bearing sulfide ores as well as carbonaceous gold ores. It is essential to characterize different types of gold ores to understand the extent and nature of gold-entrapment in different associated mineral phases before an appropriate ...
