丁基黄药在金属负载石英砂中的迁移特性.

There is a combined pollution of heavy metals and residual organic agents for mineral dressing and smelting in nonferrous metal industry area. The transport behaviors of butyl xanthate (BX) in quartz sand， Fe-coated sand and Fe/Cu-coated sand were investigated using saturated sand column experiments and mathematic model. The results show that quartz sand loading Fe (0.07mg/g) on the surface can reduce the recovery rate of BX from 89.8% to 45.3%， and it decreases by 41.5% with the doubling of iron content. When CuO was loaded subsequently on the Fe-coated sand，BX could react with Cu2+ to generate CuBX. And the transport of BX was completely inhibited when Cu was loaded within a range of 0.010~0.055mg/g. [ABSTRACT FROM AUTHOR]
