| 摘 要： | 研究了电化学调控下黄铜矿、黄铁矿在以黄药为捕收剂和无捕收剂的条件下的浮选行为以及浮选调整剂,如CaO,CaOCl_2,对黄铁矿浮选的抑制作用。发现黄铜矿,黄铁矿的分离浮选不仅依靠矿浆高pH值和高氧化作用,而且,当使用化学药剂调节矿浆电位时,还与所使用的调整剂的化学组成有关。CaOCl_2能很好地用于铜硫分离,是由于它既能提高矿浆pH值,又能产生强的氧化作用。最后讨论了浮选机理。

| Abstract: | The flotation behaviors of chalcopyrite and pyrite under electrochemical control using collector or without collector, and the effect of modifier such as CaO, CaOCL,have been investigated. Results demonstrate that the separating flotation of chalcopyrite and pyrite depends not only on high pH value and oxidation in pulp, but also on pulp potential and components of chemicals used. The CaOCl2 can be efficiently used to supply high pH value and oxidation in flotation process of chalcopyrite and pyrite. In addition, the flotation mechanism is also discussed. |
