Tantalum-niobium ore beneficiation process

Tantalum-niobium ore beneficiation roughing use the gravity concentrate equipment, the concentrate re-election usually combined with gravity plant, gold flotation plant, electric magnetic separation or smelting etc. If processing fine raw ore or with many mud, the washing plant is necessary, while using efficient grinding and classification equipment to reduce mineral mud of tantalum-niobium.

Overseas there are so many tantalum-niobium ore mine area use the trommel washing screen or scrubber to wash the raw ore and grinding by ball mill with the classifier, like as the Australian Green Booth pegmatite mine alluvial clay weathered rough processing plant. The Canada Bonike Lake tantalum ore through continuous improvement, grinding process currently used is quite distinctive. Overseas ore ore for tantalum and niobium rougher still re-election based and gravity plant with an efficient, simple process. Like as in Green Booth mine area use the jig separator to concentrate the tantalum-niobium. As the gravity concentrate plant, the spiral classifier and gold shaking table is the best machine for tantalum-niobium concentrate.

China the grade of tantalum-niobium ore is generally low, and its mineral crisp, high density. In order to ensure the grinding fineness, to avoid over-grinding, the general stage grinding stage sorting process. Jiangxi Yichun tantalum-niobium concentrate using lateral curved screen replace linear vibrating screen for screening, field exploration results showed that: a fine sieve can be reduced 14.70 percent clip, clip rough can be reduced 4.3 percent next screen, screening efficiency can be increased 17.72 %. Successfully tested the device for on-site screening stage grinding transformation provides a new way. In recent years, China has made some progress in the study of tantalum and niobium flotation plant, but because the drug prices are too high, only a few overseas tantalum-niobium mine use flotation method, such as Canada Oka, Brazil Allah Aqsa mine areas.

Crushing plant for rock ore processing

The purpose of ore crushing and grinding is grinding and size classification to reduce the ore down to a fine particle size. Generally the complete ore crushing plant consists of jaw crusher, ball mill classifier, magnetic separator, flotation machines, thickener, dryers and other major equipment, such as vibrating feeder, bucket elevator and belt conveyor. This production line feature with high efficiency, low energy, high capacity, economical and so on.

The primary crusher reduces ore from the trucks to 8-inches or less. That material goes to the primary stock pile directly that you see crushed rock falling onto in your image. Two conveyors (out of view to the right in your image) pull this material directly into each SAG mill where it is combined with water and mill balls (as needed). Big raw ores are feed to the jaw crusher evenly and gradually by vibrating feeder machine for primary crushing.

After primary crushing, the material will be transferred to other crushers by belt conveyor for secondary crushing, and then the crushed materials will be transferred to vibrating screen for separating. Final, the materials will be transferred into the ball mill evenly for ore grinding.

Flotation machine - JXSC mine machinery factory

                  

The flotation machine’s impeller is driven by V-belts, which can bring the centrifugal effect to form the negative pressure. On the one hand, to inhale sufficient air to mix with ore pulp to stir ore pulp and mix with medication to form the mineralized froth. To adjust the height of flashboard to control the liquid level and make the useful froth scraped by loam board.

When Gold ore flotation machine works, slurry is inhaled from the bottom of the trough to the space between impellers. Meanwhile, the low pressure air sent by fan is sent to this area through the air distributor in the hollow shaft. After sufficient mixing, the slurry is pushed out by the impeller, and then goes to the whole trough. When the froth rises to the stable level, after the enrichment processing, froth overflows to the froth trough from the overflow weir. Another part of ore slurry flows to lower part of impeller for the remixing with air. The remaining slurry flows to the next trough until it becomes residue.

Dry Disc Magnetic Separator - JXSC mine machinery factory

        

Dry Disc Magnetic Separator is the mining equipment of weak magnetism, which is applicable for the strong magnetism mineral less than 5mm. It is widely used to separate sand in rivers, lakes and in mineral separation factory. And it is also used to recycle industrial scoria and sulfuric-acid residue.

Used for pre-concentration in the magnetic separation mill, remove the waste stones out of the ore and restore grade.

Used for stope the recover iron ore from tailings and increase the utilization rate of ore resources.

Used for the iron and steel factories. Handle the discarded steel slag and mill scales to recover the iron.

Used for the garbage handling. Recover the useful metals and improve the quality of environment.

Small Scale Mini gold trommel

JXSC Company have made the small scale Mini gold trommel with small capacity 5-10T/H , it is suitable for washing gold ores with sticky clay, many small miners prefer this mini type, also very workable for the testing phase of big mining project.

The detail specifications of this mini scale Mini gold trommel is as below:

the drum diameter is 400mm, length of scrubber 800mm, length of screen 1300mm,one layer screen. Steel material screen. With hopper, steel wheel and gear gear driven.

We make the length of scrubber and screen according to your gold ore condition. if the material is much clay, and very sticky, we will make the scrubber a littler longer, so as to wash clean the clay. Also we accept OEM. If you have interests in this item, welcome to inquiry us at any time!

Deck Vibrating Screen - JXSC mine machinery factory

Deck Vibrating Screen uses electric exciter as vibrating source, the material will be thrown around the screen, at the same time doing forward sports, in order to achieve the screening purpose. Material from the feeder evenly enters into the machine's feeding inlet, with multilayer sieves to produce various of products and unqualified products on the screen or under the screen, then discharging from the outlet repectively. It can be used in the automatic production line.

Our Deck Vibrating Screen capacity can make 300t/h, it can make 4 layers screen, It is Widely used in plastics, abrasive, chemical, pharmaceutical, building materials, food, etc.
