10TPH Rock Tungsten Ore Extraction Flow
This is a 10 TPH (10 tonnes per hour) tungsten ore extraction production line, designed and built by JXSC for a client in Ethiopia. We tailored a complete, efficient, and controllable tungsten ore beneficiation process by combining the mineral characteristics of tungsten ore, such as “raw ore grade of 3-5%, high density, high specific gravity, weak magnetism, and fine embedded particle size”. This process integrates multiple processes such as “multi-stage crushing, closed-circuit screening, rod milling and liberation, jigging + shaking table combined gravity separation, and magnetic separation“.
1. Raw ore feeding:
Raw ore enters the raw ore feed silo from the ore pile and is fed evenly and quantitatively by the trough feeder to ensure stable and continuous feeding. Multi-stage crushing: The material is successively crushed to the appropriate particle size by a PE jaw crusher, a PEX fine jaw crusher, and a double roll crusher.
2. Closed-circuit Screening:
The crushed product is transported via belt conveyors and an intermediate hopper (equipped with a swing feeder) to a vibrating screen (configured for 2mm/6mm separation). Oversize material (+6mm) is returned to the double-roll crusher for further reduction, creating a closed-circuit loop. The finer fractions (0–2mm and 2–6mm) are fed into two jigging machines for pre-concentration, allowing for the early recovery of a portion of the 0–2mm concentrate.
3. Grinding and Liberation:
The remaining material is processed in a rod mill, followed by dewatering and classification using a spiral classifier/sand washer.
4. Gravity Concentration:
A portion of the slurry is processed through 12 shaking tables; the tailings from these tables are then fed into a second set of 4 shaking tables to recover any remaining tungsten minerals.
5. Magnetic Separation:
Another portion of the slurry is fed into a three-disk magnetic separator, which segregates the material into magnetic, weakly magnetic, and non-magnetic fractions, enabling the comprehensive recovery of multiple minerals.
6. Tailings Management:
Wastewater from the ore-washing process is directed to a settling pond for sedimentation, and tailings are stored in a regulated manner, ensuring compliance with environmental standards and facilitating the comprehensive utilization of resources.
The entire 10TPH rock tungsten ore extraction plant covers the entire process from raw ore input, multi-stage crushing, particle size screening, grinding and liberation, to gravity separation enrichment, magnetic separation, and finally the production of tungsten concentrate. Through meticulous process design and an optimized equipment configuration, the plant achieves highly efficient recovery of tungsten concentrate and effective separation of gangue minerals, ensuring a high recovery rate (over 90%), a high-grade final product (over 60%), and low operating costs.

Highlight Of JXSC Design 10TPH Rock Tungsten Ore Extraction Plant
√ End-to-End Closed-Loop Process: Seamless integration across multiple stages, with full material traceability and zero loss during intermediate handling.
√ Superior Gravity Separation: A combination of jigging (for roughing) and shaking tables (for cleaning/scavenging) is perfectly suited to the high specific gravity of tungsten ore, achieving a high enrichment ratio.
√ Precise Particle Size Control: A closed-circuit crushing system ensures optimal feed size, effectively preventing metal loss caused by over-grinding.
√ Multi-Mineral Recovery: Gravity separation recovers tungsten concentrate, while magnetic separation enables the recovery of various other minerals, ensuring high resource utilization.
√ Economical and Robust Operation: Well-matched equipment configuration minimizes over-grinding; the system is durable, stable, and features low operation and maintenance costs.
√ Green and Sustainable: Wastewater is settled and recycled, and tailings are disposed of in compliance with environmental regulations.
Given the diverse types and varying properties of tungsten ores, a one-size-fits-all production line often fails to achieve optimal results. JXSC advocates for a tailored approach, designing customized beneficiation solutions based on the specific characteristics of each tungsten ore deposit:
- Alluvial/Placer Tungsten Ore: Screening, jigging, and tabling—a simple, cost-effective process.
- Polymetallic Associated Ore: A combination of gravity separation, flotation, and magnetic separation to ensure the comprehensive recovery of valuable metals.
- Fine-Grained, Refractory Tungsten Ore: Enhanced grinding and classification paired with fine-particle shaking tables to improve the recovery rate of fine-grained material.
By providing details such as your ore type (including deposit characteristics, mineral grain size, and associated mineral composition), specific process requirements, and budget, we can develop a bespoke tungsten extraction solution for you.
