Extraction of antimony from a complex gold concentrate containing antimony in China

The use of alkaline sodium sulfide leaching method to treat a complex gold concentrate containing antimony, antimony and mineral separation and extraction, antimony recovery at the same time improve the recovery of gold. The leaching rate of antimony can reach more than 91% by 40g/l the content of sodium hydroxide, 100g/l of sodium sulfide and temperature 60℃ . The leaching solution obtained antimony content more than 97% by electrical product and realized the recovery of antimony in the gold concentrate.
