四川攀西地区某铜铅多金属硫化矿选矿试验研究

Mineral Dressing Test of Sulphite Ore from a Cu-Pb Polymetallic Deposit in the Panzhihua-Xichang Region

该处矿石铜铅分离时沿用重铬钾(K2Cr2O7)抑铅,由于重铬酸钾的使用产生了大量含铬(Cr6+)废水,严重地污染了周围的环境。受企业委托选用了无毒、无污染的选矿药剂,代替重铬酸钾。试验研究结果表明,用无毒巯基乙酸钠抑铜浮铅,可实现铜铅分离,并可获得较好的浮选指标。

Separation of Cu and Pb is completed by K2Cr207 which results in environmental pollution by a great amount of Cr6＋. A test of separation of Cu and Pb by means of C2HaNaOES without environmental pollution is a great success.
