摘要

采用环保药剂“金蝉”处理夏家店金矿,并与NaCN处理效果进行了对比研究。结果表明:当“金蝉”药剂用量为200 g/t时,金浸出率为88.55%,与NaCN浸金的浸出率(88.73%)基本相同;当“金蝉”药剂用量为300 g/t时,可获得金浸出率为89.87%的良好指标,明显优于最佳条件下NaCN浸金效果(88.73%);使用“金蝉”药剂处理金矿石后,金吸附效果及载金炭解吸效果与氰化法接近(金解吸率分别为98.99%和98.97%),无不良影响;“金蝉”取代NaCN,可明显提高技术经济指标,此外,由于“金蝉”的低毒性,可在运输、管理、环保和安全等方面产生更多隐形效益。

Abstract

Environmental-friendly reagent Jinchan was used as a substitute for sodium cyanide to treat Xiajiadian gold mine,and the leaching effect of Jinchan and sodium cyanide was compared.The results showed that the leaching rate of Jinchan and sodium cyanide was 88.55% and 88.73% respectively,which was basically the same when the dosage of reagents was 200 g/t;When Jinchan dosage was 300 g/t,the leaching rate of 89.87% could be obtained,which was obviously better than the leaching effect of sodium cyanide under the optimal conditions;When using Jinchan,the adsorption and desorption effects were the same as that of sodium cyanide,with gold desorption rate of 98.99% and 98.97%, respectively;Jinchan as a substitute for sodium cyanide,could significantly improve technical and economic indicators,and moreover,in view of the non-toxicity of Jinchan,the invisible benefits of transportation,management,environmental protection and safety also would be obtained.
