Gold extraction - Wikipedia

Hard rock ores have formed the basis of the majority of commercial gold recovery operations since the middle of the 20th century where open pit and or sub-surface mining techniques are used. Once the ore is mined it can be treated as a whole ore using a dump leaching or heap leaching processes. This is typical of low-grade, oxide deposits.

Cyanide Process - Gold Cyanidation Process Gold Leaching ...

Gold should be separated from other minerals present in the ore. As gold is insoluble, it should be separated from other minerals to make it soluble. Hence, sodium cyanide can be added, where cyanide ions form a complex ion with the molecules of gold. The cyanide process is as explained below-The ore is grounded and crushed.

Extraction of gold using cyanide

Extraction of gold using cyanide Gold is found in very low concentrations in the ore from which it is mined. To collect the gold from the ore it needs to be separated from the other minerals in the ore. To do this the gold needs to be made into a soluble form so that it can be separated from the other minerals as gold is insoluble.
