摘要:
针对某含砷铅矿石性质，进行了抑砷浮铅工艺探讨，考察了铅捕收剂、砷抑制剂等因素对铅砷分离指标的影响，并通过正交试验研究了药剂之间的协同作用。结果表明：在最佳条件下，采用石灰、硫代硫酸钠、硫酸铵组合作为砷抑制剂，丁铵黑药、乙硫氮组合作为铅捕收剂，对矿石进行抑砷浮铅选别，闭路流程获得的铅精矿铅品位46.00 %、铅回收率83.26 %，银品位1 190.00 g/t、银回收率79.77 %，含砷0.58 %；砷精矿砷品位8.81 %、砷回收率74.58 %。

Abstract:
According to the property of an arsenic-containing lead ore,the process of arsenic inhibition and lead flotation in an arsenic-containing lead ore is discussed,the effects of lead collectors and inhibitors on the flotation separation of lead and arsenic are studied,and the synergistic effects between reagents are studied through orthogonal tests.The results show that under the optimal conditions that the process of arsenic inhibition and lead flotation is carried out on the ore with the arsenic inhibitor of lime,sodium thiosulfate and ammonium sulfate combination and the lead collector of ammonium butyrate black powder and ethyl sulfide nitrogen combination,the closed circuit can obtain the lead concentrate whose lead grade 46.00 %,lead recovery rate 83.26 %,silver grade 1 190.00 g/t,the silver recovery 79.77 % and the arsenic content 0.58 %; and the arsenic concentrate whose arsenic grade is 8.81 % and arsenic recovery rate 74.58 %.
