摘　　要：夏家店金矿(秦鼎公司)解吸电解工艺及装置变更使用高温高压无氰解吸电解工艺的应用,证明了解吸电解率高,解吸的贫炭品位底,同时在金矿选别使用金蝉代替氰化钠的载金炭解吸电解效果对比及分析,也证明了高温高压无氰解吸电解工艺也适合在金矿选别使用金蝉的载金炭解吸电解的实践应用上。The application of high temperature and high pressure cyanide free desorption electrolysis process in Xiajiadian gold mine(qinding company)has proved that the desorption electrolysis rate is high and the desorbed lean carbon grade is low.At the same time,the desorption electrolysis effect of gold loaded carbon using cicada instead of sodium cyanide in gold ore separation is compared and analyzed,It is also proved that the high temperature and high pressure cyanide free desorption electrolysis process is also suitable for the practical application of gold loaded carbon desorption electrolysis of gold cicada in gold ore separation.
