Refractory Gold Ore Treatment Methods
Where gold is associated with arsenic, antimony, tellurium, and certain other minerals, it is often only partly soluble in cyanide solution. The difficulty is usually more of a physical than a chemical one but special methods of treatment may be required.

The present article summarizes antimony mine distribution, antimony mine drainage generation and environmental impacts, and critically analyses the remediation approach with special emphasis on iron oxidizing bacteria and sulfate reducing bacteria.
Bio-precipitation of arsenic and antimony in a sulfate-reducing
Arsenic (As) and antimony (Sb) from mining sites can seep into aquatic ecosystems by acid mine drainage (AMD). Here, the possibility of concomitantly removing As and Sb from acidic waters by precipitation of sulfides induced by sulfate-reducing bacteria (SRB) was investigated in a fixed-bed column bioreactor.

Roasting in Metallurgy
The antimony combines with oxygen and escapes as volatile oxide, as does also the arsenic, a portion of which is volatilised as sulphide. " The main object of the process which has been considered is the formation of soluble sulphate of silver." The reactions, however, are precisely similar in an ordinary oxidising roast.
