Tantalum-niobium production line and process solutions

Tantalum niobium ore production line and process solution

I. Program Overview

Tantalum-niobium ore is an important strategic rare metal resource, and the tantalum-niobium ore beneficiation process needs to be differentiated according to the characteristics of the ore. This tantalum-niobium production line solution provides gravity separation, magnetic separation, flotation, electrostatic separation and other process combinations, through the "roughing - selection" two-stage design, to achieve efficient recovery and separation of tantalum-niobium ore, and the grade of concentrate Ta₂O₅+Nb₂O₅ can reach more than 50%.

Second, tantalum-niobium ore dressing process program

1. Roughing section program

   • Gravity beneficiation dominant program:

     • Jigger/spiral chute (processing +0.5mm coarse grains)

     • Shaking table/centrifugal concentrator (processing -0.5mm fine grains)

     • Technical index: 15-25% of crude concentrate grade, 75-85% recovery rate

   • Combined magnetic separation-gravity beneficiation program:

     • Medium-strength magnetic separation pre-enrichment (0.6-1.0T)

     • Spiral Chute Concentration

     • Applicable to ores containing magnetic minerals

2. Concentration section program

   • Magnetic separation purification program:

     • High gradient magnetic separation (1.2-1.5T)

     • Acid washing pretreatment (remove surface iron)

     • Concentrate grade increase by 30-40

   • Flotation selection program:

     • Pharmacy regime:

       • Capture agent: oleic acid/sodium alkyl sulfate

       • Adjusting agent: Na₂CO₃+Na₂SiO₃

     • Separation efficiency ≥85%

   • Electrostatic beneficiation purification program:

     • Narrow grade classification (-0.5+0.2mm)

     • Compound electric field sorting (voltage 20-40kV)

     • Tantalum-niobium mineral recovery rate ≥90%

3. Combined process program

   • Combined gravity separation-magnetic separation-electrostatic separation:

     • Roughing: jigging + shaking table

     • Concentration: magnetic separation + electrostatic separation

     • Final concentrate grade ≥50

   • Combined flotation-gravity beneficiation:

     • Specialized for ore sludge treatment

     • Centrifugal beneficiation + flotation combination

     • Sludge recovery rate increased by 20
