A "refractory" gold ore is an ore that has ultra-fine gold particles disseminated throughout its gold occluded minerals. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. A refractory ore generally contains sulphide minerals, organic carbon, or both, generally leading to a …

The gold grade in the original ore, calculated from the dough balance, is 2.07 g/t. The gold in the ore is mainly distributed in large grades, so more than 60% of the metal is in the + 1 mm grade. Due to the fact that the bulk of gold in the ore is concentrated in large grades, there is a high probability of finding unopened metal in it.

Refractory gold-ores are characterized by low gold recoveries in direct cyanide leaching. The reasons for low recovery are sulphides, carbon or arsenic due to encapsulation or absorption effects. Oxidizing roasting of such ores prior to leaching is an effective step to increase gold recovery typically to levels well above 90%.
