采用X射线光电子能谱分析、表面吸附、Zeta电位测定和微浮选实验研究了硫离子与孔雀石表面的相互作用。结果表明，孔雀石的浮选回收率与矿浆中硫化产物及其活性组分的含量和残余硫离子的种类有关。硫化产物由一硫化亚铜、二硫化亚铜和多硫化亚铜组成。其中，二硫化物和多硫化物对产物的活性有积极的贡献。(C)2016年韩国工业与工程化学学会。Elsevier B.V.出版，保留所有权利。
The interaction between sulfide ion species and malachite surfaces in relation to flotation was studied in this work using X-ray photoelectron spectroscopy analysis, surface adsorption, zeta potential determination, and micro-flotation experiments. Results demonstrate that the flotation recovery of malachite was correlated with the contents of sulfidization products and their active components as well as the residual sulfide ion species in pulp solutions. The sulfidization product was composed of cuprous monosulfide, cuprous disulfide, and cuprous polysulfide. Among them, disulfide and polysulfide positively contributed to the activity of the product.
