Gold must be recovered from the ores it is mined from. The most popular process for recovering this gold is called cyanidation. Cyanidation is done by oxidizing and dissolving gold in an alkaline cyanide solution. When the gold is dissolved, the solution containing the gold is removed from any solids that were not dissolved in the solution.

From the perspective of metallurgical processing, gold ores can be classified into free-milling and refractory ores. Their extractive metallurgy are largely driven by mineralogical factors such as: gold particle size, association with other minerals, coatings and rimmings, presence of cyanicides, oxygen consumers and preg-robbers, presence of refractory gold minerals and locking of ...
