The lead-zinc ore production process includes: crushing, grinding, classification, and beneficiation. In the process crushing, three-stage closed-circuit crushing is a modern method suitable for high-hardness lead-zinc ore. It can complete the work of ore crushing and partial dissociation to improve the subsequent grinding efficiency. In the process of grinding, the two-stage and one-closed grinding can make the lead and zinc ore grinding more fully. Among the beneficiation processes, the most successful new process in recent years is the mixed flotation process.
It is applied to build houses, roads, and bridges. Granite is a special ore with high content of quartz and little iron. Its crystal combination is very tight. Its texture is excellent. Granite is with dense structure, hard texture, and good acid and alkali resistance. It is a corrosion-resistant material. It can be used in the chemical industry, metallurgy, thermal power, cement, printing and dyeing, national defense facilities, and other fields.
Fine process of processing technology
Each kind of material processing equipment has its special functions, and we should also make them play the greatest role in the material processing plant. It is also convenient for our customers to select and determine the appropriate equipment according to their special material processing field.
