摘　　要：针对某银多金属矿矿物组成种类繁多、矿石性质复杂、选矿难度大、选矿指标不理想等问题,开展工艺矿物学研究,分析原矿矿物组成、有价组分种类、矿石结构构造及赋存状态,并在此基础上进行探索性选矿试验研究。结果表明,该矿主要有价金属为铜铅锌银,主要金属矿物有黄铜矿、方铅矿、闪锌矿及黄铁矿,银金属主要赋存于黄铜矿与方铅矿中,探索性浮选试验较好地实现该银铜铅锌多金属矿浮选分离富集。The process mineralogy of a polymetallic ore is investigated for solving the problems of the mineral composition with great variety minerals, the complicated properties, the difficult for floating separation, and the unsatisfactory floatation index. The mineral composition, valuable components, ore structure and occurrence state are analyzed. And the exploratory mineral processing experiments are conducted. The results show that the principal valuable components are Ag, Cu, Pb and Zn, and the principal metallic minerals are chalcopyrite, galena, sphalerite and pyrite in the Ag polymetallic ore. And the most parts of Ag presents within chalcopyrite and galena. In the exploratory test, the metallic sulfide minerals are successfully separated by flotation and the satisfactory mineral processing index is achieved.
