| 摘 要： | 矿浆中Ｃａ２＋、Ｍｇ２＋的含量显著影响黑钨矿选择性絮凝效果。研究结果表明，Ｃａ２＋、Ｍｇ２＋均是通过降低颗粒表面ζ 电位而使微细矿粒之间产生凝聚或互凝，添加适量的Ｎａ２ＣＯ３可克服矿浆中Ｃａ２＋、Ｍｇ２＋的不良影响。在配水中，以ＦＤ为絮凝剂、（ＮａＰＯ３）６为分散剂，可实现黑钨矿与４种脉石矿物人工混合矿的分离。

EFFECTS OF Ca~2+ AND Mg~2+ ON SELECTIVE FLOCCULATION OF WOLFRAMITE AND ITS MECHANISM |
| |
| Abstract: | Selective flocculation of wolframite is considerably influenced by the content of Ca~2+ and Mg~2+ in pulp.Research results show that,both Ca~2+ and Mg~2+ can lower the Zeta potential on the surface of particles and cause the coagulation among fine particles.The bad effects of Ca~2+ and Mg~2+ in pulp can be overcome by adding the right amount of Na_2CO_3.In the condition of FD used as flocculant and (NaPO_3)_6 as dispersant,wolframite can be separated from four kinds of gangue minerals in mixed water. |
