Abstract

The action of the arbitrary physisorbed species of a collector at a mineral is compared with the theoretical evidence on particle–bubble attachment. The lack of the correlation between the hydrophobic behavior, characterized by the wetting angle, and the floatability of minerals, as well as the correlation between the inductance time and the mineral recovery are discussed. The causes of disagreement between the collectability sequence of xanthates, dithiophosphates and dithiocarbamates and the sequence of boost in energy of chemical bond between these reagents and cation of mineral lattice are exposed. Collectabilities of frothers and residues of the collectors are explained. The ways to increase flotation performance are shown, namely, the mineral recovery and the concentrate quality can be improved by means of adjustment of the chemisorbable /physisorbable collector ratio.

物理吸附收集器在粒子-气泡附着中的作用

摘要

将捕收剂的任意物理吸附物质对矿物的作用与粒子-气泡附着的理论证据进行比较。讨论了以润湿角为特征的疏水行为与矿物的可漂浮性之间缺乏相关性，以及感应时间与矿物回收率之间的相关性。揭示了黄原酸盐、二硫代磷酸盐和二硫代氨基甲酸盐的可收集性顺序以及这些试剂与矿物晶格阳离子之间化学键能增加顺序不一致的原因。解释了起泡剂的收集能力和收集器的残留物。显示了提高浮选性能的方法，即，
