| 摘 要： | 研究了脆琉铅锑矿与铁闪锌矿两种矿物的基本浮选行为以及铅锌浮选分离中NaCN的作用机理和模型。研究结果表明，脆硫铅锑矿的天然可浮性好于铁闪锌矿，石灰对脆硫铅锑矿物的可浮性具有明显的影响。吸附量测定表明，NaCN对脆硫铅锑矿物表面物理吸附和化学吸附的黄药解吸能力都弱于铁闪锌矿。

| Abstract: | This paper studied the fundamental flotation behaviors of the jamesonite and marmatite and the mechanism and the model of NaCN in the Pb-Zn separation. Results show that the natural flotability of the jamesonite is better than that of marmatite. The flotability of jamesonite can be effected obviously when Ca(OH)_2 is used to adjust the pulp's pH. Adsorption tests show that desorption of xanthate physically and chemically adsorbed on the surface of jamesonite is weak than that of marmatite in the presence of NaCN. |
