Gold Ore Roasting Techniques

The ore is roasted to hematite rather than magnetite—the latter condition resulting in a higher cyanide consumption. Roasting Arsenopyrite Ore for Gold The roasting of ores containing arsenopyrite presents greater difficulties than straight pyritic ores mainly because of the tendency toward the formation of insoluble arsenites and arsenates, which have a detrimental effect on gold recovery.
