Rare Earth Mineral Grinding

-- Steady & Reliable Manufacturer --

Introduction

The processing of rare earth element (REE) ores like monazite and bastnäsite is a specialized field where purity and recovery are paramount. Our rare earth mineral grinding mills are designed to meet these challenges. We focus on providing a grinding solution that achieves the necessary liberation size for separation while minimizing cross-contamination. With options for ceramic linings and specialized wear materials, our equipment ensures that the unique chemical properties of the REEs are preserved, delivering a high-quality concentrate for complex downstream hydrometallurgical processing.

Applications

  • Ore Beneficiation: Grinding of REE-bearing ores such as bastnäsite, monazite, and ion-adsorption clays.
  • Magnetic Separation Prep: Preparing the ore for the separation of magnetic REE minerals.
  • Flotation Feed: Grinding to the required size for the selective flotation of REE minerals away from gangue like calcite or barite.
  • Chemical Processing: Fine grinding of concentrates to increase surface area for efficient acid leaching.

Advantages

  • Purity Assurance: Our C-series mills feature optional alumina ceramic linings and grinding components, which virtually eliminate metallic iron contamination—a critical factor in REE processing.
  • Precise Particle Size Control: The integrated air classifier allows for sharp cuts and a narrow particle size distribution, improving the efficiency of subsequent separation stages.
  • Flexibility: The system can be easily adjusted to handle the different grinding characteristics of various REE ores, from hard rock monazite to softer clay-based deposits.
  • Compact and Clean: The entire system is enclosed and operates under negative pressure, preventing the leakage of potentially valuable or hazardous dusts.

Payment & Shipping

We support various payment methods, including T/T and L/C. Our logistics team ensures that every component is meticulously packed and labeled for safe international transport. We provide door-to-port or door-to-door services upon request, handling all export formalities for a hassle-free experience.

Frequently Asked Questions

  • Q: Why is iron contamination a major problem for REE processing?
  • A: Iron can interfere with the complex chemical separation (solvent extraction) processes used to separate the individual rare earth elements from each other. It consumes expensive reagents and can co-precipitate, leading to lower purity and recovery of the final REE oxides.
  • Q: Can the same mill be used for different types of rare earth ores?
  • A: Yes. The operational parameters of our mill, such as grinding pressure and classifier speed, are highly adjustable. This allows you to fine-tune the grinding process to suit the specific characteristics (hardness, density, liberation size) of different ores from different deposits.
