由Yarar命名的γ-浮选法是建立在控制溶液的液-气界面张力基础上的。因此,欲浮矿物的γc值应满足γc<γlv这一条件,而不需浮出的矿物应满足γc>γlv。此处γlv指液-气界面张力,γc指固体的润湿临界表面张力。本文中列出了黄铁矿、辉铜矿、黄铜矿的分选结果。同时也还证明尽管有些矿物当它们单独存在时,具有标准的γc值,但当与其他矿物混合时,相邻矿物带入的某些晶格离子成分(即使离子浓度低达0.5ppm)也会导致润湿临界表面张力发生变化。本文还证明,在传统浮选过程中无选择性浮出的某些疏水矿物,如果它们的γc值有差异,则很容易使它们达到分离。因此,可以利用添加剂来改变矿物的表面化学性质和临界表面张力,以便控制分选条件。
The gamma-flotation method, named by Yarar, is based on the liquid-air interfacial tension of the solution. Therefore, the value of γc for floating minerals should satisfy the condition of γc <γlv, and the minerals that do not need to float should satisfy γc> γlv. Here γlv refers to the liquid-air interface tension, γc refers to the wetting critical surface tension of the solid. This article lists the pyrite, chalcocite, chalcopyrite sorting results. It has also been shown that although some minerals have a standard γc value when they are present alone, some lattice ion species (even at ion concentrations as low as 0.5 ppm) introduced by adjacent minerals when mixed with other minerals Resulting in changes in the critical surface tension of wetting. The paper also shows that some hydrophobic minerals that do not selectively float in the traditional flotation process can easily be separated if their γc values are different. Therefore, additives may be utilized to alter the surface chemistry of the mineral and the critical surface tension in order to control the sorting conditions.
