Gold Extraction Process: The techniques involved in extracting gold from its ores are known as gold extraction. Once the ore has been mined, it can be processed as a whole ore utilising dump or heap leaching methods. This is typical of oxide deposits with a low grade. Prior to heap leaching, the ore is usually crushed and agglomerated.

Gold Ore

Gold ores are classified "freemilling" and "refractory" based on their response to cyanide dissolution. Bioprocessing can be used to treat refractory goldbearing 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 goldentrapment in different associated mineral phases before an .
