摘要
针对缅甸高品位白铅矿进行相关试验研究,确定采用两段粗选一段扫选的浮选流程,。通过磨矿细度,硫化钠和捕收剂的用量,硫化时间,捕收剂种类的探索研究,确定了最佳的药剂制度,在磨矿细度为85%-0.074 mm,硫化钠总用量为1250 g/t,各段硫化时间均为5 min,使用丁基黄药作为捕收剂,总用量为1500g/t,2#油为起泡剂,总用量为100 g/t时,闭路试验得到品位为59.48%,回收率为91.69%的混合铅精矿。
The experimental study for the Myanmar high-grade white lead was carried on. The flotation process of two-stage roughing one-stage scavenging was adopted. By exploring research one the grinding fineness,the dosage of sodium sulfide and collector,curing time and collector type,the best medicament method was determined. When the grinding fineness is 85%- 0. 074 mm,the total amount of sodium sulfide is 1250 g / t,the curing time is 5 min,butyl xanthate is used as a collector,the total amount is 1500 g / t,2#oil is used as foaming agent and the total amount is 100 g / t,a mixed lead concentrate with the grade of 59. 48% and recovery of 91. 69% was obtained by closed-circuit test.
