摘要
研究了温度从15℃升高到50℃时,安徽省某地石英砂矿物的反浮选特性。研究表明在矿浆pH值2～2.5时,温度为45℃,石英表面ζ电位的负值是试验温度范围内的最低值,此时长石的表面ζ电位的负值比在25℃时要大,有利于阳离子捕收剂在长石表面的吸附,从而提高长石与石英的浮选分离效果。
This paper studied the properties of quartz reverse flotation from Anhui Province when the tem- perature increased from 15℃ to 50℃. The experiment indicates that when the pH Value of the pulp is 2-2.5 and temperature is 45℃, the negative value of ζ potential of quartz surface is the lowest in the temperature range of the experiment, and the value of the feldspar is more than that at 25℃, this will be helpful for the cationic collector to adsorption on the surface of the feldspar, so as to increase the flotation separation effect between the feldspar and quartz
