| 摘 要： | Abstract: It is of important significance to make studies on the sur-face electric characteristics of flake graphite and their variation law forstrengthening the floatation of flake graphite.In this paper, DPM type microelectrophoresis apparatus is used to de-termine the surface Zeta-potential of flake graphite pure mineral, studythe affection of pulp pH value, seueral kinds of inorganic salt ions andanion surface activation agent (petroleum sodium sulfonate) on flakegraphite surface Zeta-potential,and explore the surface absorption charac-teristics of graphite.The floatation experiment of flake graphite pure mineral shows thatboth the petroleum sodium sulfonate and inorganic salt can strengthen theconventional floatation of flake graphite. The surface characteristic varia-tion caused by them is also an important factor to promote graphite floata-tion.

| Abstract: | It is of important significance to make studies on the sur-face electric characteristics of flake graphite and their variation law for strengthening the floatation of flake graphite.In this paper, DPM type microelectrophoresis apparatus is used to de-termine the surface Zeta-potential of flake graphite pure mineral, study the affection of pulp pH value, seueral kinds of inorganic salt ions and anion surface activation agent (petroleum sodium sulfonate ) on flake graphite surface Zeta-potential,and explore the surface absorption charac-teristics of graphite.The floatation experiment of flake graphite pure mineral shows that both the petroleum sodium sulfonate and inorganic salt can strengthen the conventional floatation of flake graphite. The surface characteristic varia-tion caused by them is also an important factor to promote graphite floata-tion. |
