REFRACTORY ORE PROCESSING. The common definition of “refractory” gold ores, are those ores that do not allow the recovery of gold by standard gravity concentration or direct cyanide leaching. One major category of refractory ores are gold values contained within the crystalline structure of sulfide minerals such as pyrite and arsenopyrite.

In assessing the economic benefit of the extra processing that needs to be done to improve recovery from refractory or partially refractory ores, it is always important to consider the incremental improvement in gold recovery versus standard grinding and cyanidation, and the incremental increase in costs to achieve this improvement.

“Roasting plants can be designed with a throughput up to 5,000t/d or higher per line, depending on the ore composition.” Dr Fleming says: “Prior to the 1970s, roasting was the only process available to metallurgists for treatment of refractory gold ores and it was applied in most of The advantages that Gold Fields’ BIOX offers are

mild to extremely refractory gold ores (solid solution gold). Scanning Electron Microscopy can determine the nature and occurrence of the gold and its liberation characteristics. “In the majority of cases, but not always, refractory gold ores are sulphidic in nature. This means that flotation is invariably the first process option to consider.

The majority of gold ores are classified refractory because the gold study is restricted to the processing plant and that development costs associated with mining, access to site and access to power lines and water are not included but can be considerable. Based on the mine models ore A will be a low throughput plant at 0.6 Mtpa containing
