Scheelite Beneficiation Equipment

The selection and optimization of equipment are crucial for improving separation efficiency, recovery rate, and energy consumption reduction in scheelite beneficiation. Given the characteristics of scheelite, such as fine dissemination and complex associated minerals, the following key equipment types are commonly used:

1. Fine Particle Flotation Equipment

• Centrifugal Force Field Flotation Machine: Enhances collision      probability between fine particles and bubbles through centrifugal force,      significantly improving recovery of micro-fine scheelite.

• Microbubble Precipitation Flotation Machine: Utilizes microbubble      technology to reduce bubble size, enhancing adhesion efficiency for      particles below 0.038 mm.

• Packed Media Flotation Machine: Incorporates fillers      like corrugated plates to optimize slurry flow, minimizing non-selective      aggregation.

2. Flotation Columns

• Jet Flotation Column: Generates microbubbles via high-pressure jets,      enabling rapid enrichment of high-grade concentrates.

• Cyclone-Static Microbubble Flotation Column: Combines cyclone      separation and static sorting for precise fine-particle separation with      high enrichment ratios.

• Electroflotation Column: Employs electrolysis to      produce uniform microbubbles, ideal for recovering micro-fine scheelite      from tailings.

3. Combined Separation Systems

• Column-Machine Hybrid System: Integrates the high      enrichment of columns with the high recovery of mechanical cells,      optimizing both concentrate grade and recovery.

• Magnetic-Flotation Combined Equipment: Combines magnetic      pre-concentration with flotation to enhance utilization of complex ores.

4. Auxiliary Equipment

• High-Gradient Magnetic Separator: Removes weakly magnetic      impurities during pre-treatment or tailings reprocessing.

• Centrifugal Concentrator: Enhances gravity      separation of fine particles via centrifugal force, suitable for middlings      or tailings recovery.

• Ultrasonic Dispersion Unit: Improves reagent      dispersion, particularly under low-temperature conditions.

Technological Trends

• Intelligent Control: Incorporates automation and AI for real-time      parameter optimization.

• Multi-Force Field Equipment: Develops devices      integrating centrifugal, magnetic, and shear forces to enhance      fine-particle separation.

• Energy-Efficient Design: Promotes low-power      flotation columns and optimized agitators for sustainable production.

This equipment framework ensures efficient scheelite beneficiation while addressing challenges posed by low-grade and complex ores.
