摘　　要：针对河北某含砷中细粒嵌布难选铅锌矿石的特点,通过大量探索,采用高碱条件下的铅锌依次优先浮选工艺对该矿石进行了选矿试验。试验在铅粗选时以亚硫酸钠+硫酸锌+JSY01组合药剂抑制锌硫砷矿物,在锌粗选时以硫酸铜活化锌矿物,在铅、锌精选时分别以高锰酸钾和石灰+高锰酸钾抑制毒砂,取得了铅精矿品位75.62%、回收率87.63%、含砷0.28%,锌精矿品位45.73%、回收率83.51%、含砷0.44%的良好指标,为选矿厂设计提供了依据。Due to the characteristics of fine disseminated refractory arsenic-bearing lead-zinc ore in Hebei,beneficiation tests on selective flotation of lead and zinc under high-alkaline conditions were carried out through a lot of exploration.In the rough separation test of lead,the resultant inhibitor of sodium sulfite＋zinc sulfate＋JSY01 was adopted to inhibit the zinc-sulfur-arsenic minerals,and in the rough concentration of zinc,the copper sulfate was used to activate the zinc minerals.In the final separation of lead and zinc,the potassium permanganate and the lime ＋ potassium permanganate were adopted separately to inhibit arsenopyrite.By this way,lead concentrate with grade of 75.62%,recovery of 87.63%,and arsenic content of 0.28% and zinc concentrate with grade of 45.73%,recovery of 83.51% and arsenic content of 0.44% were achieved,thus providing a basis for the design of the dressing plant.
