Basic theory and optimization of gold containing antimony ...

Gold containing antimony ore is a type of refractory gold in which gold is intimately associated with stibnite (Guo et al., 2017). When the traditional cyanidation method is used for gold extraction, thioantimonate by stibnite decomposition reacts with oxygen to form antimony acid salt, or antimony

A selective process for extracting antimony from ...

Abstract To avoid the adverse effects of antimony on the cyanide leaching process used for the recovery of gold from refractory gold ore, a cleaner production process was proposed that would selectively remove antimony as sodium pyroantimonate. The process included three steps: 1) leaching of antimony from the refractory gold ore with sodium sulfide solution; 2) pressure oxidation of the ...
