石头嘴矿选矿厂投产以来,由于矿石氧化程度深,铜铁矿物紧密共生,选别铜矿物单独使用丁基黄药捕收剂,浮选指标较低。采用异羟肟酸钠与丁基黄药混合药剂后,大幅度提高了选别指标,并降低了药剂费用。现将有关情况介绍如下。 Since the stone mouth mine concentrator has been put into operation, due to the deep oxidation of the ore and the close coexistence of copper and iron minerals, the butyl copper xanthate collector is selected for the copper mineral alone, and the flotation index is low. The use of sodium hydroxamate and butyl xanthate drug mixture, significantly improve the sorting index, and reduce the cost of medicine. The relevant information is as follows.
