The first one gave a concentrate containing $22.70, 9.4% copper, and 18% insoluble, with an extraction of 51% of the gold and …
Gold roasting technology advances and how to handle …
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%.

Getting a Handle on Refractory Ore May Determine Gold…
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 …
