摘要
对河南某钼尾矿性质进行研究,发现具有回收黄铁矿和磁铁矿的价值。在活化剂硫酸、捕收剂异丁基黄药、起泡剂松醇油用量分别为200、50、35 g/t的浮选药剂制度下,钼尾矿采用一次粗选、一次精选、一次扫选浮选闭路流程,可获得硫精矿品位41.21%、回收率87.68%的选别指标。选硫尾矿再通过一段磁选—再磨—二段磁选的工艺流程,获得铁精矿品位62.72%,全铁回收率41.86%的选别指标。
The ore property of molybdenum ore from Henan was investigated, and it was found that it was v isobutyl aluable to recycle pyrite and magnetite from the molybdenum tailings. Adopting H2S04 as activator, xanthate as collector, terpenic oil as frother, by once roughing, once cleaning and once scavenging, the pyrite concentrate grading 41.21% S was obtained by closed-circuit test, at recovery of 87.68%. Then the flotation tailings were treated by first stage magnetic separation and regrinding and second stage magnetic separation, finally the iron concentrate grade reached 62.72% while the iron recovery wa.q 41.86%.
