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 ...

The processing of gold ore involves crushing, treatment with chemicals, melting (smelting) and further purification. It is then poured into moulds where it cools and hardens as gold bars called 'bullion', which make the gold easy to stack and transport. The first stage of processing gold ore is crushing. The gold then needs to be separated from the resultant powder. Coarse gold may be removed ...
