摘　　要：针对含碳铅锌矿的性质,对预脱碳及铅浮选的调整剂和捕收剂如石灰、XYO及苯胺黑药等进行了实验.结果表明,采用预先脱碳和合理的药剂制度可获得较好的铅选别指标.在原矿铅品位为2.08%的情况下,可获得铅精矿品位47.75%、回收率75.02%.In accordance with the nature of lead-zinc ores containing carbon, regulator and collector, such as CaO , XYO , （C6H5NH）2PSSH, for pre-decarbonization and lead flotation were studied. Experimental results showed that the fairly good flotation index of lead could be obtained by pre-decarbonization and appropriate reagent regime. Under the condition that the lead grade of the crude ore was 2.08 %, the lead concentrate obtained was up to 47.75% in grade and the recovery rate was 75.02%.
