Molybdenum Ore Production Line Solution focuses on the high-efficiency recovery of Molybdenite (MoS₂) from complex sulfide ores.

This solution utilizes a "Stage Grinding - Stage Selection" flotation process to achieve a molybdenum concentrate grade of ≥ 45% and a recovery rate of 90%+, while reducing energy consumption by 30%.

What Is Molybdenum Ore Beneficiation?

Molybdenum Ore Beneficiation is the process of separating Molybdenite (MoS₂) from associated minerals like Pyrite, Chalcopyrite, and Bismuthite. Due to the natural floatability of Molybdenite, Flotation is the primary method. The challenge lies in separating it from other sulfides and preventing over-grinding of the soft Molybdenite crystals.

Molybdenum Beneficiation Process Steps

Step 1: Crushing & Screening

Goal: Reduce ROM ore to a suitable size (-10mm) for grinding.

Coarse Crushing: C Series Jaw Crusher reduces ore to 100-150mm.
Fine Crushing: HPY Multi-cylinder Cone Crusher reduces ore to -10mm.

Step 2: Stage Grinding (Crucial for Mo)

Goal: Liberate minerals while preventing over-grinding (which causes Mo loss).

Rough Grinding: MQY Ball Mill in closed circuit with Spiral Classifier.
Regrinding: Coarse concentrate is reground using a Tower Mill or Vertical Mill to ensure complete monomer dissociation.

Step 3: Flotation Separation

Goal: Selectively float Molybdenite using hydrocarbon oils.

Mixed Roughing:
Uses Non-polar Hydrocarbon collectors (Kerosene/Diesel) to float Mo and other sulfides.

Multi-Stage Selection:
3-5 stages of cleaning flotation. Uses Flotation Column to improve grade by 5-10% and reduce impurities.

Step 4: Tailings & Water Treatment

Goal: Sustainable operation with zero discharge.

Dewatering: High-Efficiency Thickener + Filter Press.
Water Reuse: Return water utilization rate ≥85%.

Process Selection Guide

Ore Type	Characteristics	Recommended Process
Single Molybdenum Ore	Simple composition.	Rough Grinding -> Roughing -> Regrinding -> Multi-stage Cleaning.
Copper-Molybdenum Ore	Contains Chalcopyrite.	Bulk Flotation (Cu+Mo) -> Cu-Mo Separation (Suppress Cu, Float Mo).
High-Carbon Mo Ore	Carbon interferes with flotation.	Pre-flotation to remove Carbon or use Carbon Depressants.

Frequently Asked Questions (FAQ)

Q1: Why is regrinding important for Molybdenum?

A: Molybdenite is soft and flaky. Grinding everything to fine size at once causes "over-grinding" (slime), making flotation difficult. Stage grinding (coarse grind -> float -> regrind concentrate) prevents this and saves energy.

Q2: How do you separate Copper and Molybdenum?

A: We use a specific inhibitor (like Sodium Sulfide or Nokes Reagent) to suppress Copper minerals while keeping Molybdenum floating. Steam heating is sometimes used to improve separation efficiency.

Q3: Can you handle low-grade Molybdenum ore?

A: Yes. Our technology (Large Flotation Cells + Regrinding) makes processing ore as low as 0.05%-0.08% Mo economically viable.
