摘要
某硫化铅锌矿含铅 ８．７９％，含锌 １３．２４％，采用一段磨矿（细度７３％－０．０７５ ｍｍ）、先浮铅、中矿循序返回的优先浮选流程及混合捕收剂乙、丁黄药和ＳＮ－９，可得到：铅精矿品位７１．５５％，回收率９１．８９％；锌精矿品位５０．３４％，回收率８５．３８％，并综合回收了伴生的镉、银．
A sulphide lead-zinc ore containing 8. 79% Pb and 13. 2% Zn was studied by adopting a preferential flotation flowsheet which comprised single-stage grinding (particle size 73% ~ 0. 075 mm), preferential flotation of Pb and middling returning in order, with xanthate ethyl, xanthate butyl and SN-9 as a mixed collector. Lead concentrate (grade:71.55% , recovery: 91. 89%) and zinc concentrate (grade: 50. 34%, recovery: 85. 38%) were obtained. The associated cadmium and silver were also recovered at the same time.
