黄药是有色金属选矿工业上应用最广泛的浮选捕收剂,也是很强的络合形成剂,对于从溶液中提取铂族金属,有不可忽视的作用。一、从大量银中选择性沉淀钯从铜、铅的冶金中间产品中提取铂族金属的传统方法是硫酸化焙烧-脱硒、碲-熔炼-浇铸金银合金-电解。但是在银电解过程
Xanthate is the most widely used flotation collector in nonferrous metal processing industry and is also a strong complex forming agent. It can not be neglected to extract PGM from solution. I. Selective precipitation of palladium from a large amount of silver The traditional method of extracting platinum group metals from copper and lead metallurgical intermediates is sulfated roasting-selenium removal, tellurium-smelting-casting gold-silver alloy-electrolysis. But in the silver electrolysis process
