摘　　要：应用2,3-二羟基丙基二硫代碳酸钠取代重铬酸钠,对西藏隆子县柯月铜铅锌矿进行了浮选分离试验研究,闭路试验获得了含铜20.57%、含锑12.76%、含银5 695.0 g/t、铜回收率78.08%、锑回收率20.67%、银回收率48.53%的铜锑混合精矿,含铅53.02%、含锑9.90%、含银1 177.0 g/t、铅回收率92.54%、锑回收率62.04%、银回收率38.80%的铅锑混合精矿和锌品位49.35%、锌回收率82.63%的锌精矿,获得了良好的经济效益和社会效益。With sodium dichromate substituted by sodium 2,3-dihydroxypropyl dithiocarbonate in the flotation of Keyue copper-lead-zinc ore from Longzi County of Tibet Autonomous Region,a closed-circuit test resulted in a Cu-Sb bulk concentrate containing 20. 57% Cu,12. 76% Sb,5 695. 0 g/t Ag,with recoveries of 78. 08% Cu,20. 67% Sb and48.53% Ag,and a Pb-Sb bulk concentrate containing 53. 02% Pb,9. 90% Sb,1 177. 0 g/t Ag,with recoveries of92.54% Pb,62.04% Sb,38. 80% Ag,as well as a zinc concentrate grading 49. 35% Zn at 82. 63% recovery. It has greatly increased effectiveness of ore processing and has brought both economic and social benefit.
