摘　　要：西藏某银铅多金属矿矿石为典型的矽卡岩型铅锌银矿石,该矿石中主要有用金属矿物为方铅矿、闪锌矿、铅钒,贵金属矿物主要是硫化银矿、自然金。针对矿石性质,采用铅银部分混合-硫化锌-氧化铅浮选的工艺,使用新型药剂LW61为捕收剂,得到的小型试验指标为:铅银混合总精矿,含银4254 g/t,银回收率80.93%;含金4.05g/t,金回收率70.09%;含铅47.35%,铅回收率84.19%。锌精矿含锌53.36%,锌回收率74.59%。浮选技术指标较好,为该矿产资源的开发提供了技术参考依据。A mixed Ag and Pb polymetallic ore inTibe belongs to the typical skarn type Pb, Zn and Ag ore, the main useful ores of which are galena, sphalerite and lead vanadium and the noble metal ores of which are sulfide silver and natural gold. In light of the ore properties, the process of lead and silver being partly mixed--flotation of zinc sulfide and lead oxide was adopted by using the new reagent LW61 as the collector. The indexes of the bench-scale test were that the lead and silver mixed concentrate contained 4254 g/t of silver and its recovery was 80.93% ,4. 05g/t of gold and recovery of 70.09% ,47.35% of Pb and recovery of 84.19% and the zinc concentrate contained 53.36% of zinc and its recovery was 74.59%. The technological indexes of flotation were relatively good, which pro- vides technical reference for the development of the mineral resources.
