SGS has developed a series of testing and mineralogy assessment protocols that allow us to determine the character of refractory gold and the mass balance between refractory and freemilling gold. Once the deportment or textural associations of the gold is determined and the mass balance known, flowsheet options are developed. Gold in sulfide ...

REFRACTORY GOLD. By definition, refractory gold ores contain gold that is resistant to extraction by conventional chemical processing and as a result responds poorly to traditional gold cyanidation techniques such as CarboninLeach (CIL), yielding less than 80% of the contained gold. Refractory gold consists of extremely fine grained gold particles that are either physically encapsulated ...

Refractory gold ores may be defined as those which yield low recoveries of gold when treated by the conventional grinding and cyanidation process. This refractory behaviour can vary from mild to severe with gold recoveries of 85% down to less than 30% [1]. A common cause of refractoriness is encapsulation of fine gold within the matrix of sulphide minerals, particularly arsenopyrite and pyrite ...

Gold roasting is a process, applicable to refractory ores and concentrates that contain sulfide sulfur, organic carbon, and potentially arsenic. Removal of these compounds is necessary to achieve high gold recovery (>90%) during cyanide leaching. Gold roasting is typically a metallurgical fluidized bed process.
