A selective process for extracting antimony from refractory gold 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 …
