本文研究了在碱性(pH:9—10)和自然pH(8—8.5)以及存在Cu~(2+),Fe~(3+),Fe~(2+)离子的情况下,金川磁黄铁矿对丁黄药的吸附和它的浮选特性。对其作用机理,作了简要的分析和讨论。试验表明,磁黄铁矿对丁黄药的吸附密度与其可浮性存在一致对应关系,Cu~(2+),Fe~(3+)离子能强化磁黄铁矿的浮选,Fe~(2+)离子无明显影响。 In this paper, in the case of alkaline (pH: 9-10) and natural pH (8-8.5) and in the presence of Cu 2+, Fe 3+ and Fe 2+ ions, Adsorption of Pyrite on Pyrite and Its Flotation Properties. Its mechanism of action, made a brief analysis and discussion. The experimental results show that the adsorption density of pyrrhotite on pyrrhotite has a consistent correspondence with its floatability. Cu ~ (2 +) and Fe ~ (3 +) ions can strengthen the flotation of pyrrhotite, 2+) ion had no significant effect.
