中文摘要: 采用氯酸钠浸出—亚硫酸钠还原工艺从金泥中提金，考察了氯酸钠用量、盐酸用量、浸出时间、温度和硫酸添加量等对金浸出率的影响以及电位对金还原率的影响。结果表明，在液固比2︰1、氯酸钠用量为矿量的5%、盐酸用量1 mol/L、时间1 h、温度85 ℃、硫酸添加量40 g/L的条件下，金浸出率高于98.5%；控制电位600~700 mV，金还原率高于97%，金粉中金品位达到68.5%以上。
Abstract:Gold was extracted from gold mud by process of sodium chlorate leaching and sodium sulfite reduction. The effects of sodium chlorate dosage, hydrochloric acid dosage, leaching time, leaching temperature and sulfuric acid dosage on gold leaching rate and effect of potential on gold reduction rate were investigated. The results show that gold leaching rate is 98.5% above under the optimum conditions including ratio of liquid to solid of 2︰1, sodium chlorate dosage of 5% of mass of ore, hydrochloric acid of 1 mol/L, time of 1 h, temperature of 85 ℃, and dosage of sulfuric acid of 40 g/L. Gold reduction rate and gold grade in gold powder is 97% and 68.5% above respectively by controlling potential at 600~700 mV.
