Xilin lead zinc mine in Heilongjiang province, beneficiation plant in June 1967 put into operation. The design scale is 1200 tons of raw ore. Introduction to mineral deposits and ores Xilin high school mesothermal deposit is filled with lead and zinc multi-metal deposit. The main mine is No. 1 ore body and is lenticular. There are two types of ore industry: dense block and disseminated. The former is 70% and the latter is 15%. Sphalerite - Iron ore is the major sphalerite minerals zinc, closely associated with pyrrhotite, galena, yellow copper ore. Sphalerite itself does not contain silver , but only small inclusions of silver minerals are present. The galena is the main lead mineral in the ore. It is distributed in the gap between the sphalerite and pyrite or distributed along the sphalerite crack or scattered in the gangue. The galena itself does not contain silver, but silver with fine inclusions tetrahedrite, sulfur, copper, silver, antimony, magenta silver, silver and other brittle silver-containing minerals and a high silver content, as the main carrier of the present silver ore minerals. Mineral processing production index of Xilin Lead and Zinc Mine Concentrator Plastic Injection Insert Molding 1. The combination of the easiness of molding and bending of resin and the rigidity, strength and heat resistance of metal can make complex and sophisticated metal-plastic integrated products sturdily.

2. In particular, the combination of the insulation of resin and the electrical properties of metal can meet the basic functions of electrical products.
3. The pre-forming combination of multiple inserts makes the post-engineering of product unit combination more reasonable.
4. Insert products are not limited to metal, but also cloth, paper, wire, plastic, glass, wood, wire ring, electrical parts and so on.
5. For rigid parts and flexible parts on rubber sealing pad, the complex operation of arranging sealing ring can be eliminated after the integrated products are made by injection molding on the matrix, which makes the automatic combination of the following process easier.
6. Because it is the fusion of molten material and metal insert, compared with the pressing molding method, the metal insert gap can be designed to be narrower, and the reliability of composite product molding is higher.
7. Suitable resin and molding conditions may be used for sealing and fixation of susceptible products such as glass, coils, electrical parts, etc.
8. Inserts can also be completely sealed into the resin by selecting the appropriate mold construction.
9. After the insert is molded, it can also be made into a product with hollow grooves along with the core hole.
10. The combination of vertical injection molding machine and manipulator, the whole row device of insert products, etc., the insert forming engineering can be mostly automated production.
