摘　　要：通过对锡石多金属硫化矿工艺矿物学研究,矿样中主要有价元素Sn和Cu的含量分别为0.38%和0.67%。其中,锡石是锡主要的载体矿物,黄铜矿是铜最主要的载体矿物锡石的粒度较粗;在细度-75μm占65%条件下,各目的矿物的解离水平整体较高各粒级的分布率随粒度的减小而减小,黄铜矿的粗粒级分布不均匀,各粒级的分布率基本随着粒度的减小而减小。By mineralogy study on cassiterite polymetallic sulfide ore, the contents of the main valuable elements Sn and Cu were 0.38% and 0.67% respectively, among which cassiterite is the main carrier in the tin ore, chalcopyrite copper is the most important carrier of coarse-grained mineral cassiterite. On the condition of the fineness -75μm accounting for 65%, there is the overall higher dissociation level of the object minerals. With the decrease of grain size, the distribution rate decreases. The coarse grain level distribution of chalcopyrite is not uniform, and the distribution rate of each grain level basically decreases with the decrease of grain size.
