Tungsten ores are mainly divided into wolframite and scheelite.Wolframite is the most important ore to extract tungsten.It is also called wolframite.Wolframite is brown to black with metallic or semi-metallic luster.Scheelite is granular in shape, white with yellow and fat luster.Orange, double cone-shaped crystals with large crystals and transparent, deep orange.Coexisting with calcite muscovite and black cassiterite, scheelite and calcite are fluoresceins.Heated or uv irradiated, slightly purple.It is the main raw material for tungsten smelting.[/vc_column_text]2 how is the extraction of tungsten?tungsten ore processing methods are mainly hand selection, aviation model selection, gravity separation, flotation, magnetic separation and electrostatic separation.In the tungsten processing plant, the extraction of wolframite is mainly gravity separation while white ore is mainly flotation.In order to comprehensively extract useful components, improve product quality and recovery rate of tungsten concentrate.The combination of mineral processing and smelting technology improves baking and leaching and other wet refining methods.In general, the tungsten ore processing machine of heavy selection is generally used, and the ore dressing of tungsten ore with a high degree of dissociation of the monomer is basically the same as the ore dressing of gold ore, and the better ore dressing index can be obtained by simple screening.For extraction of tungsten ore with a low dissociation degree, it is often necessary to break the secondary structure by bar grinding and other processes, so as to improve the recovery rate and concentrate grade.The basis of the gravitational separation of sand tin ore processing machine is also the principle of gravity separation.According to the specific gravity difference between tin ore and waste stone, the proportion of tin and waste stone in the tin deposit is very good, and the beneficiation effect can be obtained by the method and equipment of heavy separation in tin ore processing plant.At the same time, the advanced tungsten ore processing plant has the advantages of high efficiency, energy saving, environmental protection and so on, the investment of equipment is small, and the operating cost is low.It is an ideal choice for the beneficiation of sands.The equipment for gravity separation of sand tin ore is mainly jig concentrator.Sometimes, the rocking bed is also used to improve the recovery rate of fine-grained tin ore.The technological process of gravity separation for sand tin ore is screening, jigging and dewatering.For the sand tungsten ore with a low degree of dissociation, two reelection processes are often needed: screen jig, rod mill, jigging and dewatering.Jxsc mine machinery company in china has more than 30 years of professional experience at tungsten ore processing plant, design full set tungsten ore process flowchart, provide complete set tungsten ore processing plant, can send an engineer to mine site for equipment installation and commissioning guidance.Have already built many tungsten ore processing plant in africa countries.Include china, brazil, bolivia, malaysia, nigeria, myanmar, australia, mongolia, kenya, etc.Below are the flowchart description that jxsc engineer recommend for the tungsten ore processing plant tungsten ore processing plant, the extraction of tungsten flowchart as below feeding-> crushing->grinding->primary separation -> final concentration-> upgrading the feeding way, primary separation, final concentration and tungsten ore refining process are almost the same as above alluvial/sand tungsten ore processing plant.Below are the crushing and grinding stage description for rock tungsten ore processing plant: crushing: for crushing the big rock tungsten ore stone to a smaller size before grinding.Crushers can be rough rock tungsten ore jaw crusher, rock tungsten fine jaw crusher, rock tungsten cone crusher, rock tungsten hammer crusher, roller crusher rock, depends on the rock tungsten ore feeding size and process capacity to use which kind crusher.Grinding: after crushing the stone to a smaller size, need to grind to power by tin ore ball mill grinding machine or wet pan mill or other rock grinding machine, so the tungsten concentrate can be released out from stone.Then go to the gold separation machine and concentration machine( tungsten ore shaking table).Extraction of tungsten research also has a positive effect on the extraction of tungsten from scheelite, extraction of tungsten from molybdenum, extraction of tungsten from wolframite, extraction of molybdenum and tungsten.Jxsc provides a full of mining equipment of tungsten mining process, wolfram mining, gold processing and so on mineral exploration plant.More news: how to use tungsten tailings?.

The biggest characteristic of the sag mill is that the crushing ratio is large.The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm.The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mills crushing ratio is smaller.The feed size is usually between 20-30mm and the product size is 0-3mm.

Rod mills are very similar to ball mills, except they use long rods for grinding media.The rods grind the ore by tumbling within the the mill.Rod mill is widely applied in metal and nonmetal mine, water conservancy, glass and construction materials industries, mainly suitable f more.

Size and proportion of grinding medium in the ball mill, the size and proportion of steel balls have a great influence on the productivity and working efficiency of the mill.For coarse and hard materials, larger steel balls should be selected, for fine and brittle materials, with smaller diameter steel balls, the impact times of steel balls in the mill increase with the decrease of ball diameter, and the grinding between balls increases.The clearance is dense with a decrease of spherical diameter.Therefore, it is better to choose the ball with a larger mass and smaller diameter (loose density) as the grinding medium.The size of the ball mainly depends on the particle size of the material to be ground, and the diameter and speed of the mill can be considered appropriately.Formula (1-15) is an empirical formula for spherical diameter and feed size.Dmax the maximum diameter of steel ball, mm; amax the maximum size of feeding granularity, mm.After calculating the maximum steel ball diameter, the steel ball ratio in the mill can be calculated with reference to fig.2-1 (suitable for cement mill, other mills can refer to).After choosing the maximum diameter and minimum diameter of steel balls according to technological requirements, material properties, mill specifications and various parameters, and then matching grade, using curves, the accumulative percentage of the mass of each corresponding steel balls loaded into the mill can be found, the actual percentage of the mass can be calculated, and the loading quality of steel balls at all levels can be obtained.According to the production practice of production enterprises, the relationship between ball diameter and material size is shown in table 1-11.A kind of steel balls are gradually worn out in the process of grinding materials.The wear of drop steel ball is related to its impact force.The wear of grinding steel balls is related to the surface area of steel balls.In general, the steel ball in the grinder has both impact and abrasion effects, so the wear is proportional to the n power of the diameter of the steel ball, and the value of n is between 2 and 3.Table 1-11 the relation between steel ball diameter and material size.
