How to Recover Mercury from Cinnabar Stibnite Ore

 · The possibility that recovery of an antimony byproduct would offset additional costs of treatment led to a preliminary investigation of concentration of cinnabar-stibnite ores. The results of this study indicated that a possible recovery process included bulk flotation of the sulfides, followed by oxidation roasting with close control of temperature and atmosphere.

Extraction of gold from Stibnite Ores

Extraction of gold from Stibnite Ores The removal of antimony from a refractory gold-bearing stibnite ore by roasting and selective chlorinating roasting was investigated. The influence of roasting temperature, roasting time, roasting atmosphere and type and amount of chlorinating agents on antimony removal were studied.
