about tantalite-columbite mineral separation

Columbite-tantalite ore is usually multi-metal minerals of tantalum, niobium, tin, tungsten, lithium, beryllium etc. It is usually complex about composition with its low content, big density, and crisp nature. The main method to separate tantalum-niobium is gravity separation, magnetic separation, floatation separation, and chemical treatment while in most situation combination flow sheet will be adopted. Usually, the whole columbite-tantalite processing line covers rough separation and fine selection.

Gravity separation is the main way to beneficiate columbite-tantalite ore while sometimes combination of gravity separation-floatation separation-gravity separation, gravity separation-floatation separation, and gravity separation-magnetic separation-floatation separation can be involved.

About the gravity separation of raw columbite-tantalite mineral enrichment, muilti-milling and multi-gravity separation is mainly used. During the separating machine is usually for each milling machine to recover the liberated columbite-tantalite granules. Crushing and milling is usually not needed for columbite-tantalite sand ore with its high degree of dissociation. Screening is used before gravity rough separation to remove the block stone or gravels, and the fine output from screen can be separated by columbite-tantalite jig separator. The rough concentrate from jigger can be upgraded further by shaking table.

Niobium ore magnetic separation machine is kind of magnetic beneficiation equipment. For Niobium ore, it needs liberation of niobium liberation from the impurities. Niobium mineral are usually together with magnetite, so magnetic concentrator can help to get niobium concentrate mixed with iron. This magnetic separator has a feeding size range of -5mm with a big treatment capacity, a high recovery rate and great concentration efficieny.

Coltan / Columbite Description: Coltan / Columbite occurs mainly in granitic pegmatite veins and albitized and greisenized granites. It coexists with quartz, feldspar, muscovite, lepidolite, beryl, topaz, zircon, cassiterite, wolframite, monazite, barite, thorite, etc., Color: Brownish black to iron black (the color of columbite ore and tantalum manganese ore is lighter) Hardness: 4.2 (columbite) 7 (tantalum manganese ore) Specific Gravity: 5.36~8.17 Streaks: Dark red to black Gloss: Semi metallic to metallic, translucent to opaque Useful: Mainly used to produce special alloy steels for military industry and advanced technology Distribution: Democratic Republic of Congo, China, Canada, Brazil, Russia, Nigeria, Zaire, Kenya, Tanzania, etc.,

Coltan / Columbite Mining Coltan / Columbite mines have open-pit mining or underground mining. The mining process usually contains washing, screening, gravity separation and magnetic separation. Sometimes crushing is also needed if the ore is too big.

Coltan is mined by hand in the Congo Congo has a group of coltan mined by hand. The hand mining method is to dig basins in streams and scrape mud from the surface. The water around the crater was stirred so that the coltan ore settled to the bottom of the crater, and the miners retrieved it. This mining method has a great impact on the environment. Manual selection is gradually eliminated, and the other methods have a progressive development.

Coltan / Columbite Mining Equipments on Sale Vibration Screen: Classic, Universal and Standardized Screen Vibrating screen is a screening equipment with vibrating motor as vibration source, which is a classic, universal and standardized screening machine. Its screening accuracy is high, and corresponding the capacity is not too high. The capacity of our vibrating screen is about 10-500t/h and the layers of the screen can be from 1 to 4.

Spiral Chute: High Efficiency Gravity Separation Equipment Spiral chute is generally used as roughing equipment, which can discard most of tailings to get coarse concentrate. It is suitable for separating non-ferrous metal, rare metal and non-metallic mineral bodies with particle size of 2-0.02mm. Such as iron ore, ilmenite, chromite, pyrite, tungsten ore, tin ore, tantalum ore, niobium ore, etc., The beneficiation process of our spiral chute is stable, easy to control, the allowable variation range of feed particle size is large, the enrichment ratio is high, and the recovery rate is high.

Magnetic Separator : Fit For Your Various Need Magnetic separator is widely used in resource recovery. Its suitable for the magnetic separation of magnetite, pyrrhotite, ilmenite, limonite, hematite, manganese and other materials with a particle size of less than 3-5mm. It is also used in the removal of iron from coal, non-metallic minerals, building materials and other materials. Magnetic separator is one of the most widely used and highly versatile machines in the mining industry.

The magnetism of minerals is different, so we supply weak, medium and strong magnetic separators. There are magnetic separators work in dry and wet in our product line. Permanent and electromagnetic magnetic separators are all on sale. Our magnetic separator line is very rich that can fit your various needs.

Ball Mill: Key Equipment to Crush The Ore After The First Crushing Ball mill is usually used as the second or last crusher for the ore with particle size less than 20mm. The capacity of our ball mill is about 1-95t/h and the discharge is 0.074-0.4mm. The dry grinding and wet grinding, lattice type and overflow type ball mill can be found in our mining products. The common ratio of steel balls, materials and water is 4 :2: 1 for our ball mills.
