Experimental research of pyrite type difficult leachable gold ore concentrate

QIAN Fang-jun,LI Deng-xin,LI Qing-cui(Donghua University,Shanghai 201620,China)  
Oxidation pretreatment through ozone is made to pyrite-like difficult leachable gold ore concentrate.Under the set technological oxidation conditions,the gold=bearing pyrite is easily decomposed thus Fe and S are leached out.Test is done to survey the effect of airflow,reaction duration temperature,slurry density and FeCl2 6H2O addition on oxidation pretreatment process thus to determine the best conditions for pretreatment.
