Title: Processing of Gold-containing Slag from Sulfuric Acid Production Using Sulfatizing Roasting Followed by Chlorine Leaching
Abstract: Sulfatizing roasting and chlorine leaching of refractory gold-containing slag from sulfuric acid production have been investigated. The effects of sodium chlorate dosage, sodium chloride dosage, liquid-solid ratio, leaching time, reaction temperature and pretreatment condition on leaching recovery of gold have been studied. The results show that the leaching rate can reach as high as 91.44% under the optimum conditions that the addition of NaClO3 is 100 kg/t, the addition of NaCl is 80 kg/t, the liquid-solid ratio is 3, the leaching temperature is 80℃ and the leaching time is 4.0 h.
