Tantalum Niobium Ore Processing
Tantalum niobium ore refers to the general term for minerals containing tantalum and niobium. This can be used for ore mining & processing, mainly from tantalite(coltan), niobium iron ore(columbite), and pyrochlore.
JXSC supports custom full tantalum-niobium ore processing flow and equipment, including washing, crushing, grinding, gravity concentration (core), and magnetic separation (purification), and other beneficiation processes. High-purity sorting and enrichment capabilities, eco-friendly and compliant, durability and safety.
Application: It applies to the treatment of coltan, columbite, and tantalum-niobium ores with cassiterite coexisting, etc.
Tantalum niobium ore beneficiation process
The ta-nb (coltan, columbite) ore beneficiation separates the valuable minerals in the raw ore from impurities to obtain high-purity concentrate, which meets the requirements of industrial applications. The specific Ta-Nb ore process should be determined according to the specific nature and composition of the ore.
- Tantalum niobium washing: To extract tantalum-niobium ore with large mud and strong viscosity, washing operation is essential; usually adopt large-scale trommel scrubber.
- Tantalum niobium crushing & grinding: The mined tantalum and niobium ore is first crushed by crushers and then sent to a ball mill to ground fine powder.
- Tantalum niobium gravity separation: If raw ore contains niobite, cassiterite, zircon sand, ilmenite, tantalite and other valuable metals, the specific gravity difference is relatively large; usually use jig to gravity separation the ta-nb ore composite concentrate with good purity. Shaking tables can separate concentrate or waste tailings and multiple products can be obtained at the same time.
- Tantalum niobium flotation: This method is usually used to separate non-metallic minerals such as opal and quartz in tantalum-niobium ore.
- Concentrate separation: The concentrate after rough separation may still contain certain impurities; comprehensive use of magnetic separation, electric separation, etc. to further improve the grade and recovery rate. Three-disc magnetic separators are often used to achieve the one-time separation of multiple minerals.
The tantalum-niobium ore dressing process is determined mainly based on the properties of the original ore. Contact us to customize small to large tantalite, coltan, columbite, tin, and tantalum-niobium ore process and equipment with the best recovery rate for you.

Alluvial Tantalum niobium tin processing flow
1. Feeding: The truck loads the raw material into the first vibrating feeder equipped with a 70mm mesh screen. +70mm will be sent to the transfer bin by the 1st conveyor.
2. Screening: 0-70mm materials will be sent to trommel screens with 8mm and 15mm screens for washing and separation. The 0-8mm material will be sent to the vibrating screen with 2mm sieve for separation again. The 8-15mm material is sent to two jig for separating. 15-70mm material will also be sent to the transfer silo.
3. Gravity separation: After vibrating screen separation, the 0-2mm material is sent to two jigs; each jig will be equipped with two shaking tables for further separation. The 2-8mm material is sent to two jig separators for separating. After passing through the jig, the 2-8mm and 8-15mm concentrates are directly sent to the drying field.
4. Crushing & Drying: The material in the transfer bin will be fed into the primary jaw crusher by the second vibrating feeder under the bin. The primary jaw crusher output will be sent to the secondary crushing, crushing to 0-20mm. The secondary crushed material is sent to the hammer crusher for crushing. 0-2mm will be stored in a pool with water. They will then be pumped to the remaining two jigs equipped with two vibrating tables for further separation. All the concentrates in the shaker are sent to the drying field for drying in the sun or in a rotary dryer.
5. Magnetic separation: The three-disc magnetic separator separates the dried 0-2mm concentrate. Eventually, it will be separate magnetite, ilmenite or hematite, tantalum-niobium concentrate, and non-magnetic materials.
JXSC provides professional process flow design, which can accurately separate tantalum-niobium ore, improve recovery rate, and concentrate grade. Contact us to customize small to large scale tantalum-niobium-tin processing plants and get the latest quote for equipment!
2. Rock Coltan Processing plant
- Coarse and fine crushing: Coarse and fine jaw crushers.
- Screening and grinding: Vibrating screens, ball mills, spiral classifiers.
- Gravity separation: (1) Spiral chutes: This system performs two-stage sorting (roughing + concentrating), with middlings returned for re-sorting to improve recovery.
(2) Shaking tables: The roughing and concentrating products are combined and fed into the shaking table, achieving a high recovery rate of 95%, enriching coltan and associated rare metals. - Magnetic separation: A three-disc dry magnetic separator for enhanced purity.
The 50TPH rock coltan processing plant, using the optimization of the whole process of “crushing-grinding-gravity-magnetic separation”, achieves efficient enrichment and purification of various rare metals (tin, tungsten, tantalite, ilmenite).
