Gold Extraction Procedure From Antimony Ore

The clean production process for extracting antimony from refractory gold ore involves sodium sulfide leaching pressure oxidation concentration and crystallization steps. First the stibnite in the refractory gold ore reacts with sodium sulfide and antimony is dissolved into the leaching solution in the form of sodium thioantimonite Eq.
