摘要

本文研究了波兰KGHM公司开采的含铜页岩zeta电位随pH值的变化规律。在水和选定的浮选起泡剂水溶液中进行了测量。结果表明,含铜页岩在水中分散后,在pH=3.5时出现等电点(IEP)。起泡剂的加入降低了pH值的IEP,丁醇的IEP为1.93,MIBC为2.90,二十碳二醇十六烷基醚(C16E20)为2.76。在引入泡沫改变的情况下,zeta电位变得不那么负。本文采用两个可调参数的经验方程来近似zeta电位- ph曲线的过程。该方程很好地逼近了所研究页岩在水或泡沫水溶液中的zeta电位。

ZETA POTENTIAL OF POLISH COPPER-BEARING SHALE IN THE ABSENCE AND PRESENCE OF FLOTATION FROTHERS
In this paper, zeta potential as a function of pH of copper-bearing shale, which is mined in Poland by KGHM, was investigated. The measurements were conducted in water and aqueous solutions of selected flotation frothers. It was established that for investigated copper-bearing shale, after dispersion in water, the isoelectric point (IEP) occurs at pH=3.5. Addition of frothers decreased the IEP on the pH scale and the IEP for butanol was 1.93, for MIBC 2.90 and for eicosaethylene glycol hexadecyl ether (C16E20) 2.76. In the case of introducing frothers changed, the zeta potential becomes less negative. An empirical equation, having two adjustable parameters, was used in the paper to approximate the course of the zeta potential-pH curve. The equation showed a very good approximation of the zeta potential of the investigated shale either in water or frother aqueous solutions.
