重有色金属硫化矿石是所选别的矿物原料中很有意义且极难选的矿种之一。一般来说，有色金属各类型矿石大部分都含硫化矿物和非硫化矿物，不均匀，细粒嵌布，而且浮选性质相近，这些类型的矿石的处理工艺，各有特点，因而在制订新的有效的技术措施时，都要考虑到这一点。同时， Heavy non-ferrous sulphide ore is one of the most interesting and extremely difficult minerals in the selected minerals. In general, most of the non-ferrous metal ores contain sulphide minerals and non-sulphide minerals, which are inhomogeneous and finely-grained, and their flotation properties are similar. The treatment processes of these types of ores have their own characteristics. Therefore, Effective technical measures, we must take this into account. Simultaneously,
