Gold ores are considered refractory if gold extractions from a conventional cyanidation process are less than 80 even after fine grinding. 1) Arsenic-bearing refractory gold ore has stones extremely difficult to deal with. In the stones, gold is locked up in arsenic mineral matrix as the form of microscopic or submicroscopic lattice.

A significant contemporary challenge for gold mining companies is to define economic process options for treating complex ore bodies as the less refractory ores become depleted. Demonstration of economic treatment options allows gold companies to maintain and increase their ore reserves.
Because gold in such ores is very fine particle form wrapped with arsenic, the leach reagents are unable to reach it in cyanide leaching process. 2) The gold ores with As must be broken or decomposed in the gold particles scales, so that gold is fully exposed, and then extracted with the appropriate gold leaching agent. The process of crushing or decomposition before gold leaching is called pretreatment of refractory gold.
