| 中文摘要: |
| 针对难处理含金硫酸渣进行了硫酸盐化焙烧-氯化(氯酸钠-氯盐)浸出试验研究，考察了氯酸钠用量、氯化钠用量、液固比、浸出时间、浸出温度、焙烧预处理等因素对金浸出率的影响。研究结果表明，在优化的试验条件:氯化钠用量为80 kg/t，氯酸钠100 kg/t，反应温度80℃，液固比为3，反应时间为4 h下，处理该含金硫酸渣可以得到91.44%的金浸出率。 |
| 英文摘要: |
| 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. |
