为了探索黄铁矿和砷黄铁矿进一步分离的可能性,将一定量的含金精矿在添加还原调节剂的条件下,采用浮选进行了实验室试验。在这些工业产品中金与砷紧密共生,在含盐硫化物(连二亚硫酸钠和亚硫酸钠)存在的条件下,用黄药在酸性介质中对黄铁矿进行浮选试验,结果发现砷黄铁矿能够被分离出来。对不同参数如矿浆pH值、捕收剂和调节剂浓度进行了研究,获得了有价值的结果。
In order to explore the possibility of further separation of pyrite and arsenopyrite, laboratory experiments were conducted using flotation of a certain amount of gold-bearing concentrate with the addition of a reducing regulator. In these industrial products, gold and arsenic are closely intergrown, and in the presence of salt-containing sulfides (such as sodium dithionite and sodium sulfite), pyrite flotation experiments with xanthate in an acidic medium have revealed that arsenopyrite Can be separated. Different parameters such as pulp pH, collector and conditioner concentrations were studied, and valuable results were obtained.
