Beneficiation cost of Wolframite gravity concentration equipment

Wolframite is usually in coarse grain or slab * * body embedded state in the ore, and the associated gangue is mostly quartz vein. The boundary between Wolframite and quartz vein is obvious, with a large difference in proportion. According to the gravity concentration theory, the various properties of Wolframite conform to the beneficiation and purification of gravity concentration method. After many tests and practices, it is really proved that the grade of Wolframite is improved or the beneficiation cost of Wolframite gravity concentration equipment is relatively low. The Wolframite dressing equipment mainly includes crushers, round vibrating screens, rod mills, feed warehouses, feeders, hoppers, dewatering screens, conveyors, etc. The combination of these equipment forms a gravity dressing production line for Wolframite, which not only has the advantages of energy conservation, efficiency, and environmental protection, but also has the advantages of small equipment investment, low production cost, and high dressing efficiency.

The Wolframite gravity concentration process of most plants is similar to this. By utilizing this process, most factories can produce qualified concentrates, while some factories can produce coarse concentrates and send them to selected factories for processing. At present, the principles and processes of gravity separation adopted in China include: first to second stage grinding, third stage skip, fourth to fifth stage shaking table, centralized treatment of fine mud, coarse concentrate, and disposal of large amounts of tailings; Coarse and medium sized jumping tailings enter the rod mill for further grinding, and the grinding products return to the double vibrating screen, forming a circulating closed circuit. There are generally two options for a shaker, coarse and medium particles are returned to the circulation circuit in the shaker, and the ore slurry is treated separately. Wolframite beneficiation equipment is favored because of its low beneficiation cost, simple equipment structure, less environmental pollution and suitable conditions.

Wolframite gravity concentration equipment 6S shaker can be divided into coarse sand shaker can be divided into coarse sand (slot 46 and 60), fine sand (slot 90 and 110), slime (slot 120 and 138). The bed surface can be divided into single wave, double curved wave, and floating bed surfaces, made of fiberglass. The rack can be made of large and small channel steel. The S-shaker is a process that combines mechanical vibration and water flushing to separate ore particles in proportion. The S-shaker is the main beneficiation equipment for gravity beneficiation, and the notable feature of the 6S shaker is its high enrichment ratio, which is commonly used to obtain the final concentrate. At the same time, it can separate the final tailings and effectively treat fine-grained minerals. The sorting particle size is 3mm. If tin ore and Wolframite are selected, the lower limit is 0.4mm, and iron ore can reach 0.074mm, which is mostly used for separating materials below 1mm. The mineral particle group starts from a feeding trough at the upper corner of the shaking table surface at 6mm, and the horizontal flushing water is provided by the trough. Therefore, under the action of gravity, horizontal flow impact, inertia and friction generated by the asymmetric reciprocating motion of the bed surface, the mineral particles are layered according to proportion and particle size, and move vertically along the bed surface, while moving horizontally along the inclined bed surface. Mineral particles with different proportions and particle sizes gradually flow along their respective directions of motion, and are discharged from different areas on the concentrate end and tailings side of the shaker, ultimately divided into concentrate, intermediate ore, and tailings.

The working principle of Wolframite separation with mineral processing shaking table is that the separation of shaking table is realized under the joint action of bed surface and horizontal water flow. The bed strip or carving groove on the bed surface is perpendicular to the direction of water flow. When water flows horizontally, eddy currents form in the grooves. The combined effect of eddy current and bed shaking causes the mineral sand layer to loosen and layer according to density. Heavy minerals shift towards the lower layer, while light minerals shift towards the upper layer. This process is called separation and layering. The upper layer of light mineral particles is greatly impacted by water flow, while the lower layer of heavy mineral particles is less impacted. Therefore, the horizontal motion speed of light mineral particles on the bed surface is greater than that of heavy mineral particles on the bed surface. In the longitudinal direction, the differential movement of the bed surface (initially advancing slowly and gradually accelerating, suddenly retreating when the speed reaches its maximum, gradually decreasing in speed during the retreating process, and then advancing. Repeating the above process) not only promotes the loose layering of the ore layer, but also causes heavy mineral particles to move forward longitudinally at a higher speed, causing light mineral particles to move forward at a smaller speed. The direction of mineral particles depends on their longitudinal and horizontal velocities. The synthesis speed of heavy minerals shows that the heavy mineral end has a smaller longitudinal velocity.

Six advantages of 6S shaker for Wolframite beneficiation 1. The transverse slope adjustment range of the shaker is greater than 0-10 degrees, and the stroke adjustment is convenient.

2. Compared to wood, FRP does not absorb moisture, bubble swelling, dry cracking, mold, and moths. The bed surface is flat, has good corrosion resistance, is sturdy and durable, is not easily deformed, and is convenient for local repair.

3. When changing the lateral slope and stroke, the bed surface of the shaking table can also maintain stable operation, and the spring is placed inside the chassis, with a compact structure.

4. The bedside mechanism operates reliably, with fewer easily worn parts and no oil leakage.

5. Chemical corrosion resistance, acid and alkali resistance, and avoiding the use of mineral processing agents in pulp

6. No reagent consumption, high enrichment rate, clean sorting, and low power consumption.

The Wolframite gravity separation equipment is used for separation according to the ratio difference between useful Wolframite and waste rock. Generally, water is used as the medium for re selection, and mineral particles in different proportions are re layered in a periodic alternating medium flow to obtain two or more mineral flows with different proportions. This process can be called Wolframite gravity concentration process. For example, if the machine jumps, the material evenly enters the machine. Under the encouragement of the jumping machine diaphragm, the material entering the jumping machine can be re layered in a vertically alternating water flow. Layered materials with larger and smaller specific gravity have a faster settling speed than minerals with larger proportions, located in the lower layer of the skip machine sorting tank.

The dynamic jump LTA series of Wolframite gravity concentration equipment can meet the different dressing needs of large, medium and small tungsten ore dressing plants. The downward jump LTA series of transmission structure and adjustment device are designed reasonably, and the operation and maintenance are simple. The dressing effect is remarkable. It is unique among diaphragm jump machines.

The skip machine is one of the effective equipment to improve the grade of Wolframite. It is mainly used to pre recover coarse and medium grained Wolframite, and can also be used to pre concentrate and discard the tail of low-grade Wolframite. The main function of the shaker is to select and purify the coarse concentrate of Wolframite selected by the skip machine. The mineral types of Wolframite and other mineral partners (such as pyrite) also need to be separated with a shaker to improve the grade of Wolframite. Whether it is a skip or a shaker, it is the embodiment of the gravity concentration method for Wolframite selection, and it is also the most widely used beneficiation method for Wolframite selection. The combination of skip machine and shaker can make the best effect of Wolframite selection. According to the ore properties of Wolframite, it is necessary to design reasonable beneficiation process and equipment configuration for Wolframite selection.

The down acting skip is one of the earlier LTA types of Wolframite skip selected by Chinese mines. Because of its simple and compact structure, convenient adjustment, simple operation and maintenance, and remarkable beneficiation effect, this series is unique among diaphragm skip. The LTA series of lower motion skip is mainly used for the treatment of metal smelting slag such as silicomanganese slag, ferrochrome slag, ferronickel slag, manganese ore, lead zinc ore, celestine, Baryte, fluorite ore, pyrite, Limonite, Hematite and other metal and non-metallic minerals. The LTA series is a single row double chamber, also known as a downward moving conical diaphragm jumping machine. LTA uses water as the medium and performs sorting based on the ratio (density) difference between minerals and gangue. The beneficiation principle is based on the theory of gravity beneficiation. The jumping cycle curve generated by the normal operation of the LTA series jumping machine is sinusoidal, with the characteristic of uniform upward water flow. This series of skip machines has the advantages of large processing capacity, high recovery rate, and continuous operation in mineral processing. The LTA series of downward jumping machines utilizes an eccentric linkage mechanism to make the rocking frame move up and down, pushing the vertebral body to move downwards, encouraging the water flow to generate periodic pulsation curves, and achieving mineral processing effects. The LTA series of skip machines have a lower transmission, compact structure, small footprint, and large processing capacity, which are widely used in the field of skip beneficiation.

The grinding process of Wolframite beneficiation equipment is to use energy to extrude, impact and grind ores to separate useful mineral monomer in Wolframite, which is conducive to the selection process in the next stage. Crushing is the use of mechanical energy to compress ore, causing it to break and peel off. According to the crushing theory, the energy consumed to achieve a certain particle size through crushing is less than the energy consumed to achieve the same particle size through grinding. This is also the origin of commonly used crushing schemes in engineering, but this only considers energy consumption. In engineering construction, many factors should be considered, such as process length, links, positions, floor area, investment, operating costs, and impact on the environment. What grinding process should be considered. At present, the grinding process of large and medium-sized Wolframite concentrators (except for coarse crushing) mainly includes cone crusher, roller crusher, semi-automatic mill and ball mill. Cone crusher is the fastest developing equipment in the past 20 years, and it is also the fastest developing equipment in the past 20 years- As an effective equipment for reducing energy consumption, rolling presses have also been selectively applied in recent years based on their characteristics.

The gravity concentration method to improve the grade of Wolframite is mainly based on the ratio difference between Wolframite and gangue. The settling speed of different mineral particles in the medium flow is different. Therefore, Wolframite and gangue with different proportions can be layered according to the proportion, which is equivalent to abandoning gangue and improving the grade of Wolframite. According to the specific properties of Wolframite, the design of reasonable gravity concentration process and equipment configuration will help to improve the grade of Wolframite.

Improving Wolframite grade is not only an ideal method for Wolframite beneficiation because of its low equipment investment, low production cost, high beneficiation efficiency and no pollution to the environment. Although the Wolframite recovery process is simpler, the high magnetic equipment costs high and consumes high power, and is mostly used for Wolframite slime recovery. For Wolframite raw ore and coarse embedded Wolframite, the high magnetic selection is rarely used.

The density of Wolframite is high, and gravity concentration is one of the main beneficiation methods for tungsten ore. This method dominated before the 1970s, such as Pine Creek in the United States, Yxsjoberg in Sweden, and famous mineral processing plants such as Xihuashan and Hukeng in China all using gravity separation technology. Up to now, most Wolframite ores still use gravity concentration. Gravity separation is somewhat obvious, cost-effective, and beneficial for environmental protection. However, due to the low processing capacity of gravity separation equipment, poor fine mud recovery rate, and limited development, after entering the 1970s, gravity separation was silent and replaced by flotation. Many newly expanded factories adopt flotation technology. By the late 1970s, with the development of high-efficiency and high-capacity beneficiation equipment and gravity separation equipment, as well as the development of automatic control technology, gravity separation had restarted in tungsten beneficiation.
