Double-Refractory Carbonaceous Sulfidic Gold Ores ...

Jan 01, 2016· The roaster was built using a single-stage fluidized bed, aimed to oxidize both the gold-bearing sulfides and TCM in one stage. However, as the ores feeding the roaster became more complex, recovery in a single stage decreased, primarily owing to the formation of a less porous calcine at the high temperatures required to oxidize the TCM.
