Wolfram Beneficiation Production Line and Process Solution

Wolframite Beneficiation Production Line Solution is designed for Quartz-Vein type Tungsten deposits.

This solution adopts "Gravity Separation as the core", covering Roughing, Gravity Separation, Cleaning, and Fine Mud Treatment. It efficiently recovers Wolframite ((Fe,Mn)WO₄) and associated metals like Tin and Molybdenum, achieving a concentrate grade of WO₃ ≥ 65%.

Step 1: Roughing (Pre-concentration)

Goal: Discard waste rock early to reduce downstream load.

• Crushing: Jaw Crusher reduces raw ore size.
• Jigging: Movable Screen Jig processes coarse particles. Tailings are discarded immediately, while coarse concentrate goes to the next stage.

Step 2: Gravity Separation (Core Stage)

Goal: Recover Wolframite based on density difference.

• Multi-stage Jigging: Trapezoidal Jigs process medium-sized particles.
• Shaking Table: Shaking Table processes fine-grained tailings from jigs.
• Closed Loop: Middlings are returned for regrinding to ensure maximum recovery.

Step 3: Cleaning & Purification

Goal: Remove Sulfides and separate Wolframite from Cassiterite/Scheelite.

Step 4: Fine Mud Treatment

Goal: Recover Tungsten from slime (often 20% of total metal).

• Uses Centrifugal Concentrators or Flotation to recover fine tungsten, tin, and bismuth minerals that gravity separation might miss.

Project: Large-Scale Wolframite Plant

• Raw Ore Grade: 0.8% WO₃
• Wolframite Concentrate: 68% WO₃ (92% Recovery)
• By-products: Tin (85% Recovery), Sulfur (35% Grade)

Q1: Why is "Over-Crushing" bad for Wolframite?

A: Wolframite is brittle. If over-crushed into fine slime (-0.037mm), it becomes very difficult to recover by gravity separation, leading to huge metal loss. We use Stage Grinding and Jigs to recover coarse particles early.

Q2: How do you separate Wolframite and Cassiterite?

A: Both are heavy minerals. However, Wolframite is weakly magnetic, while Cassiterite is non-magnetic. We use High-Intensity Magnetic Separation to separate them effectively.

Q3: Can you treat the fine mud/slime?

A: Yes. For fine mud, we use Centrifugal Concentrators or specialized Flotation reagents to recover the fine tungsten values, increasing total recovery by over 20%.
