According to the characteristics of black tungsten coarse grain inlay, a three-stage jigging is implemented. The coarse and middle two-stage jigging tailings are dewatered by a spiral classifier and then fed into the rod mill. The final grain size requirement of the grinding is greater than 1.7mm, the fractional content is less than 15%, the content less than 0.074mm is less than 12%, and the rod mill and double layer vibrating The sieve constitutes a closed circuit. The double-layer vibrating screen is less than 1.7mm into the fine-grain jig and the jig tailings into the hydraulic classifier. The hydraulic classifier divides the ore less than 1.7mm into four grades and sends them to the shaker for sorting. The shaker is selected for two-stage operation, and the second-stage shaker is re-grinded in the ore. The grinding grain size is less than 0.5mm and the grain content is 85%. After the second-stage grinding product is graded, it is then selected into the shaker and selected from the original ore. The separation of the 1.7mm grain grade ore is separated into separate treatment systems to form a lean and rich sort.

Compared with other processing technologies, such as flame cutting, plasma processing, laser cutting, EDM cutting, cnc milling, water cutting does not produce harmful gases or liquids and does not generate heat on the surface of the workpiece. Water jet cutting is truly versatile, efficient, and cold-cutting. Water cutting directly uses the kinetic energy of the abrasive water jet to cut the metal to achieve the perfect cutting purpose. no chemical change during the cutting process, no influence on the physical and chemical properties of the cutting material, no thermal deformation, narrow slit, high precision, smooth cut surface, clean and pollution-free, and can process traditional processing and Other processing methods can't process or hard to process materials, such as glass, ceramics, composites, reflective materials, chemical fiber, heat sensitive materials. 3 Axis Water Jet Cutting Machine Aluminum Cutting Machine,3 Axis Water Jet Cutting Machine,Waterjet Cutting,Small Waterjet Cutting Machine HARBIN QIAN FAN XI FENG MACHINERY CO.LTD , https://www.waterjetwamit.com
The primary slime and secondary slime are treated centrally, and the sorting equipment is mainly based on the grooved mud shaker and the spring shaker.
The re-election process fully considers the characteristics of the wolframite, and adopts three-stage jigging, four-stage shaker, mud-sand sorting, lean-rich sorting, shaker-mine re-grinding and other processes, especially multi-stage Jigging, the recovery rate of jigging accounted for 62.61% of the re-election.
See the table below for the recovery index of each equipment unit in the re-election section. The process flow and mineral processing indicators are shown in the following figure: 
Water Jet Cutting Machine advantages showing:
(1) The roughness of when cutting metal is 1.6μm, and the cutting precision is ±0.10m, which can be used for precision forming cutting;
(2) No reflection effect and edge loss in the cutting of non-ferrous metals and stainless steel;
(3) only need one time to cut carbon fiber composite materials, metal composite materials, metal composites with different melting points and non-metals;
(4) Cutting of low melting point and flammable materials, such as paper, leather, rubber, nylon, felt, wood, explosives, etc.;
(5) Cutting under special site and environment, such as underwater, flammable gas environment;
(6) Cut high hardness and insoluble materials, such as stone, glass, ceramics, cemented carbide, diamond, etc.
