| 摘 要： | 研究从青海滩涧山氰化尾渣回收金银的过程。结果表明,采用焙烧、加煤焙烧、中温氯化焙烧、硫酸预处理工艺效果均不理想,而采用高温氯化法时金银回收效果良好。在氯化钙添加量5%、焙烧温度1 200℃、焙烧时间1 h时、金挥发率达到89.57%,银挥发率53.46%,同时,铁基本不挥发,砷有少量挥发。

| Abstract: | The recovery of gold and silver from residue of roasting-cyaniding process in Tanjianshan of Qinghai is investigated.The recovery is unsatisfactory with the process of roasting,roasting with coal adding,middle temperature chlorination roasting and sulfuric acid pretreatment,respectively,while the desired recovery is achieved with the high temperature chlorination process.The gold and silver recovery rate was 89.57% and 53.46%,respectively,under the condition of 5% calcium chloride addition,temperature 1 200... |
