超声波清洗对方铅矿、闪锌矿和黄铁矿可浮性的影响

在进行单矿物可行性研究中,为消除硫化物矿物表面的氧化膜对可浮性的影响,浮选前常进行矿物的清洗。清洗时间短、工艺简单的超声波清洗是有效的方法之一。本文介绍了会泽铅锌矿6号矿体的三种硫化物矿物———方铅矿、闪锌矿和黄铁矿的超声波清洗方法,并结合单矿物的浮选试验,对超声波清洗前后矿物的可浮性做了对比研究。采用X射线光电子能谱(XPS)研究了超声波清洗前后矿物的表面特征。试验结果表明,经超声波清洗后硫化物矿物的可浮性显著提高。

EFFECT OF ULTRASONIC CLEANING ON FLOATABILITY OF GALENA, SPHALERITE AND PYRITE

In the feasibility study on pure minerals, in order to eliminate the effects of oxide film formed on the floatability of the surface of sulfide minerals, minerals are normally cleaned before floatation. Ultrasonic cleaning is one of the most effective methods, which needs short time and is easy to operate. This study investigated the effect of the ultrasonic cleaning methods on three sulfide minerals-galena, sphalerite and pyrite of the Huize Lead-Zinc Ore No. 6 ore body. Comparative tests have been performed on the floatability of the minerals before and after ultrasonic cleaning, combined with floatability tests pure minerals. The surface characteristics of the minerals before and after being cleaned by ultrasonic were studied by XPS. The test results indicate that the floatability of sulfide minerals was greatly improved after ultrasonic cleaning.
