本文研究了Ca~(++),Fe~(+++)离子及添加腐植酸钠对石英和赤铁矿悬浮液稳定性的影响,测定了矿物在药剂溶液中的ζ电位。结果表明,一定浓度的腐植酸钠对石英和赤铁矿均具有分散作用。对其作用机理也进行了探讨。
In this paper, the effects of Ca ~ (++), Fe ~ (+++) ions and sodium humic acid on the stability of quartz and hematite suspensions were studied. The ζ potential of minerals in the solution was determined. The results show that a certain concentration of sodium humate has a dispersion of quartz and hematite. The mechanism of action is also discussed.
