氰化尾渣是氰化提金过程中产生的固体废弃物，同时也是高价值的二次资源，含有大量的铜、铅、锌等有价元素。由于氰化过程长时间的充气搅拌，氰化尾渣的矿物界面发生严重的改性，但是关于这方面的研究较少。本文针对某高铜铅氰化尾渣浮选过程中存在铜铅难分离及铜回收率低等问题开展黄铜矿界面性质研究，采用的研究方法包括粒度分析仪、XRD分析、SEM–EDS微界面分析、FTIR分析、界面洗脱及浮选实验等。实验结果表明部分黄铜矿表面致密包裹一层细粒的方铅矿，导致黄铜矿表现为类似于方铅矿的浮选特性，导致这种现象的原因是黄铜矿表面被非极性油污染。不能被浮选回收的黄铜矿表面包裹一层铁矾类似物，导致黄铜矿表面被钝化而不利于药剂的吸附。通过研究可知氰化尾渣中黄铜矿界面容易被杂质污染及氧化层包裹，导致其难于被浮选回收。
The interface characteristics of cyanide tailings are different from those of the raw ore. In this study, valuable elements could not be thoroughly recovered via the flotation of cyanide tailings from Shandong, China. The interface and floatability of these tailings were investigated by phase analysis and flotation tests. The chalcopyrite in the cyanide tailings was fine and had a porous surface. The floatability of 68% chalcopyrite was similar to that of galena in the presence of a collector. A layer of fine galena particles compactly wrapped the chalcopyrite. The chalcopyrite recovery sharply decreased as the nonpolar oil residue in cyanide tailings was extracted using alcohol; however, this removal had no effect on the galena. The remaining chalcopyrite in the flotation tailings was covered with an oxidation layer consisting of O, Fe, S, Pb, Cu, Zn, and Si.
