摘要
通过单矿物试验,研究了单斜磁黄铁矿的浮选行为。结果表明：单斜磁黄铁矿在丁黄药或乙硫氮体系中的可浮性基本一致,矿浆电位对其浮选行为影响不大。碱性条件下,乙硫氮对单斜磁黄铁矿的捕收能力比丁黄药强。以丁黄药为捕收剂时,在酸性、中性和弱碱性条件下,腐植酸钠＋氯化钙组合抑制剂可很好地抑制经CuSO4活化的单斜磁黄铁矿;在NaOH形成的强碱性条件下,该组合抑制剂很难抑制活化的单斜磁黄铁矿;而在CaO形成的强碱性条件下,即使采用单一腐植酸钠也可以实现对活化单斜磁黄铁的抑制。
The flotation behavior of the monoclinic pyrrhotite was studied through the single mineral tests.The results showed that the floatability of the monoclinic pyrrhotite in the system of butyl xanthate or sodium diethyldithiocarbamate（DDTC） is nearly the same,and its pulp potential has little influence on the flotation behavior.The sodium diethyldithiocarbamate（DDTC） has better ability to collect monoclinic pyrrhotite than butyl xanthate in the alkaline condition.Taking butyl xanthate as collector,and in acid,neutral or low-alkaline condition,the monoclinic pyrrhotite activated with CuSO4 can be nicely depressed by the combination reagent of sodium humic acid and calcium chloride.In the high alkaline condition of NaOH,the activated monoclinic pyrrhotite is difficult to be depressed by this combination reagent.While,in the high alkaline condition of CaO,the activated pyrrhotite can be depressed basically with the addition of sodium humic acid only.
