Mining Industry

GN separation and conveying equipment is widely used in the separation and conveying of ore and minerals in the mining industry. GN mining vibration screens are used for the separation of ore and minerals, including coarse sieving mining vibration screen and fine separation mining vibration screen. GN mining centrifuge is all-around equipment in the mining industry especially in the treatment of ores and minerals. GN mining centrifuge is widely used in the mining of all minerals, raw materials and ores. GN screw conveyor plays an important role in the transportation of minerals in the mining industry. GN solids vacuum pump plays an irreplaceable role in the transportation of mining slurry. With strong self-priming ability and high solid content material handling capacity, GN solids vacuum pump is often used to transport mineral slurry from mineral pits or to transport mineral bulk materials over long distances.

Decanter Centrifuge GN decanter centrifuge uses high-speed rotating centrifugal force, the G force can reach 3000G. It is widely used in solid-liquid separation of minerals, mineral concentration and dewatering. The decanter centrifuge in the mining industry usually adopts more advanced wear-resistant technology to extend the service life of the decanter centrifuge in mineral separation. Compared with the filter press, the decanter centrifuge is of smaller footprint, high degree automation, and simple operation.

Horizontal Screen Scroll Centrifuge GN Horizontal Screen Scroll Centrifuge for Fine Coal is used for fine coal dewatering in coal washing plant, and well-applied coal particle range is 0-3mm. The fine coal with water in this particle range is also called coarse slime. GN Horizontal Screen Scroll Centrifuge can remove the moisture in the fine coal or coarse slime by a high centrifugal force, and the coarse slime is discharged due to the differential speed between the scraper and the screen basket. GN Horizontal Screen Scroll Centrifuge adopts horizontal installation design to replace the traditional vertical scraper discharge centrifuge. The advantages are as following of that the replacement of wear parts can be realized in the horizontal direction, the height of the workshop is greatly reduced, the failure rate is lower, and the stability is better, which is the development trend of coarse slime dewatering equipment at home and abroad. GN Horizontal Screen Scroll Centrifuge for Fine Coal is a serialized product; the screen basket diameter is from 900mm to 1200mm, which meets the processing capacity demand from 30 tons/h to 120 tons/h. After dewatering by GN Horizontal Screen Scroll Centrifuge, the surface moisture of coarse slime is about 12-16%.

Screen Bowl Decanter Centrifuge GN Coal Dewatering Screen Bowl Decanter Centrifuge is used for dewatering of ultrafine coal in coal washing plant, and well-applied coal particle range is usually 0-0.5mm. The Coal Dewatering Screen Bowl Decanter Centrifuge is with screw propeller inside the bowl. Its straight bowl section is closed type and similar to Decanter Centrifuge, and the cone bowl section has mesh holes on it. GN Coal Dewatering Screen Bowl Decanter Centrifuge adopts the principle of "centrifugal sedimentation" and "centrifugal filtration" to carry out solid-liquid separation. Ultrafine coal slurry enters the centrifuge through the feed pipe, and goes through two stages of centrifugal sedimentation and centrifugal filtration, with the help of centrifugal force, finally comes out three products, Dewatered Coal, Filtered Water and Centrifugal Water. The filtered water can be re-entered into the centrifuge as circulating material. GN Coal Dewatering Screen Bowl Decanter Centrifuge is a serialized product; there are 5 models with bowl diameter from 900mm to 1600mm, and processing capacity from 10 tons/h to 100 tons/h. The surface moisture of ultrafine coal is about 14～24% after dewatering by GN Coal Dewatering Screen Bowl Decanter Centrifuge.

Slant Plate Clarifier Slant Plate Clarifier is widely used in the sedimentation treatment of minerals. The principle is to use gravity to make solid particles to fall on the surface of the slant plate and fall down to the sludge collection trough. The clarified wastewater flows out via outlet at the top of the slant plate clarifier. The slant plate clarifier is of large handling capacity and low cost; but the discharged solid is high moisture, which requires further dewatering treatment.

Solids Vacuum Pump GN solids vacuum pump is a pneumatic pump with strong self-priming ability, vacuum degree up to 25 inches of mercury, and discharge head up to 80 meters. It can transport solids, liquids, and solid-liquid mixtures. GN solids vacuum pumps are widely used in the mining industry for mineral suction, mud transportation, and long-distance transportation of bulk materials. Unlike other rotary conveying pumps, GN solids vacuum pump has no rotating parts; therefore, it has better wear resistance in mineral transportation.

Mining Industry Common Application

Ore Treatment The ore treatment technology is very diverse and is becoming more and more important. Especially in the production of precious metals and base metals, ore treatment plays a key role. In this technology, GN separation and conveying equipment is applied in different ore treatment areas of the mining industry: iron ore, lead ore and zinc ore, gold ore, silver ore, nickel ore, copper ore, platinum ore, lanthanide elemental ore.
Minerals Treatment Minerals have a large number of application possibilities and treatment methods: from the ceramics industry to the cosmetics and coatings industry, from simple machining to the use of chemical processes, everything is possible. The minerals treatment widely uses GN separation and conveying equipment: coal mine, porcelain clay mine, bentonite, calcium carbonate, barite mine, titanium dioxide, zinc sulfate, aluminum hydroxide and other minerals. GN mining shale shaker is used for the front-stage screen separation of minerals, and the decanter centrifuge is used for the solid-liquid separation of minerals or the dewatering treatment of tailings. Unlike other companies that only provide standard equipment, GN can also provide complete mineral conveying and separation systems.
Tailings Treatment With the increasing emphasis on environmental protection all over the world and the scarcity of water resource, every country has continuously improved tailings treatment technology in the mining industry. In the exploration of metal mining, the slag discharged after extracting has formed a large number of tailings. With the expansion of the production scale, the tailings accumulation has increased year by year, not only occupying a large amount of land, polluting the atmosphere, surface water and groundwater, but also causing a huge safety hazard to the tailings stock as many tailings ponds are overdue or overloaded. At the same time, the construction and maintenance of tailings warehouses also request a lot of money, so tailings treatment is an urgent matter currently. The core equipment for tailings treatment is decanter centrifuge. The continuous separation treatment of tailings by decanter centrifuge has obvious advantages over magnetic separation, floating separation, and gravity separation. Its advantages are: pollution-free, low energy consumption, large treatment capacity, obvious effect on fine-particle materials, small footprint, and wide application range.
Coal Dewatering In the process of coal washing in coal preparation plant, it is very important to dewater the coal and slime. GN can provide clients with 0.5-50mm coarse coal dewatering equipment-horizontal vibratory centrifuge, 0-3mm fine coal (coarse coal slime) horizontal screen scroll centrifuge, as well as coal dewatering screen bowl decanter centrifuge for ultrafine coal slime dewatering below 0.5mm. In addition, GN solid bowl decanter centrifuge is also used for ultra-fine coal slime dewatering and coal tailings treatment.
