本文报导了用哈利蒙德管对提纯了的硅孔雀石进行某些浮选研究,其结果证实当矿样加热到550℃时,使用戊基黄药浮选硫化的矿样取得了很大的改进。使用十二烷基硫酸纳进行浮选,同样也取得相当好的效果。但是经热处理的矿样,使用阳离子捕收剂浮选回收率并没有获得改善。电泳迁移率的测定以及使用苯代替空气来捕收硅孔雀石矿粒的浮选研究表明,热处理后的矿物浮游性的增加有以下两个原因:(一)铜离子可溶性的增加以及铜离子在矿物表面的吸附;(二)由于一些游离的硅烷醇基团在矿物表面上的聚合作用增加了颗粒固有的疏水性。
This paper reports the use of a Harmonic tube for some flotation studies of the purified silicon malachite. The results confirm that the flotation of sulfide samples using amyl xanthate gained a great deal when the samples were heated to 550 ° C improvement of. The use of sodium lauryl sulfate flotation, also achieved very good results. However, heat-treated mineral samples, using cation collector flotation recovery rate has not been improved. Electrophoretic mobility measurements and the use of benzene instead of air to capture silicon malachite ore flotation studies have shown that the heat treatment after the increase in mineral floating for two reasons: (A) the increase in copper ion solubility and copper ions in Adsorption on mineral surfaces; (ii) The inherent hydrophobicity of the particles due to the polymerization of some free silanol groups on the mineral surface.
