黄铁矿与砷黄铁矿的共生矿石,其中含有分散的有色金属硫化物,同时含有贵金属和稀有金属,在细磨的条件下,利用氨基酸捕收剂,采用直接优先浮选法,可以回收这些金属。较为适宜的方法是,首先在粗磨的条件下,分选出硫化矿物的混合精矿,然后混合 Pyrite and arsenopyrite ore symbiotic ore, which contains dispersed non-ferrous sulfide, also contains precious metals and rare metals, fine grinding conditions, the use of amino acid collector, the use of direct flotation method can be recycled These metals. More appropriate method is, first, under the conditions of coarse grinding, sorting mineral sulfide concentrate, and then mixed
