摘要
研究氨氰洗涤贵液采用钢棉置换吸附回收金的可行性。结果表明,贵液在电压2 V、给入流速10mL/min(吸附时间1.83h)吸附置换金、铜,金吸附置换率超过95%,载金钢棉通过传统硝酸除杂、王水分金、亚硫酸钠还原得到合格金锭。
The feasibility to recover gold from ammonia cyanide solution by steel wool replacement adsorption was studied.The results show that gold adsorption replacement rate is 95% above under the conditions including voltage of 2V,feeding flow rate of solution of 10 mL/min（adsorption time of 1.83 h）by adsorption replacement of gold and copper.Qualified gold is obtained from gold-bearing steel wool by traditional process of purification with nitric acid,gold dissolution with aqua regia,and reduction with sodium sulfite.
