Gold extraction - Wikipedia

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. These refractory ores require pre-treatment in order for cyanidation to be effective in recovery of the gold. A refractory ore generally contains sulfide minerals, organic ...

Roasting metallurgy Britannica

The most important operations are roasting, smelting, and refining. Roasting, or heating in air without fusion, transforms sulfide ores into oxides, the sulfur escaping as sulfur dioxide, a gas. Smelting (q.v.) is the process used in blast furnaces to reduce iron ores. Tin, copper, and lead ores are also smelted.

2016-05-27  I'm hoping our HEPP process can either eliminate or significantly reduce the roasting step (12-18 hours at 600-700 degrees C), which is currently required for the recovery of precious metals from sulfide laden ores. If so, our process consumes a fraction (4 cents per ton) of the energy of roasting.
