砷黄铁矿是一种复合矿,它含有有色金属和贵金属。随着这种矿石处理量的增加,迫切需要作出抉择,或把砷和尾矿一起弃掉,或把它分选成砷产品和混合产品。在砷黄铁矿矿石中稀散有色金属的含量有不少达到0.01—0.15％。在这种矿石中金主要与硫化物呈胶态-低分散缔合,银则呈磺酸盐存在。与金不同,有色金属和银不总是与砷共生。在采金部门当用氰化法处理这种矿石时,磺酸盐中的银进入了尾矿,甚至有色金属也损失掉了。砷黄铁矿的明显的矿物学特征和工艺特征,决定了稀散的有色金属和银必须以优先
Arsenopyrite is a complex ore that contains both nonferrous and precious metals. With the increased handling of such ores, there is an urgent need to make a decision, either to discard the arsenic along with the tailings or to sort it into arsenic products and mixed products. In the arsenic pyrite ore scattered non-ferrous metals content of many reached 0.01-0.15%. In this ore, gold is predominantly colloidal with sulphide - a low-dispersion association with silver present as sulphonate. Unlike gold, non-ferrous metals and silver do not always coexist with arsenic. In the gold sector, when cyanide is used to treat this ore, the silver in the sulfonate goes into the tailings and even non-ferrous metals are lost. The obvious mineralogical and technological characteristics of arsenopyrite determine that non-ferrous metals and silver must be given priority
