摘要/Abstract

摘要： 针对有色金属采选场地存在重金属与残留选冶有机药剂复合污染问题，本文以丁基黄药(butyl xanthate，BX)为代表，基于饱和砂柱迁移实验和数学模型，分析了BX在石英砂、覆铁砂和覆铁铜砂中的迁移规律.结果表明，石英砂表面负载Fe量为0.07mg/g时，BX迁移的回收率从89.8%下降至45.3%，并且负载Fe量每增加一倍，BX迁移回收率平均下降41.5%.在覆铁砂上继续负载氧化铜，BX与Cu²⁺之间反应生成CuBX，在负载Cu量0.010~0.055mg/g时完全抑制了BX在介质中的迁移.

Abstract: 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.

Key words: butyl xanthate (BX); Fe-coated sand; Fe/Cu-coated sand; transport; mathematic model
