High Intensity Magnetic Separator Solutions for Industrial Mineral Processing

Addressing Critical Mineral Separation Challenges

Industrial operators face persistent challenges in mineral beneficiation:

• Contaminant carryover reduces final product purity by 8-12%, triggering downstream processing costs of $18-$35 per ton
• Ferrosilicon losses in dense media plants account for 15-20% of operational budgets annually
• Magnetite buildup causes 3-5 hours weekly maintenance downtime in iron ore circuits
• Non-magnetic recovery rates below 92% force reprocessing of 500+ tons monthly

Are your current separation methods delivering measurable ROI? Can your plant afford another quarter of preventable material losses?

High Intensity Magnetic Separator Operational Overview

Equipment Type: Permanent Rare-Earth Roll Magnetic Separator
Process Flow:

1. Feed material enters vibratory chute at controlled throughput rates
2. Primary magnetic roll extracts strongly paramagnetic particles (>5,000 Gauss)
3. Secondary roll captures weakly magnetic materials (1,000-5,000 Gauss)
4. Splitter system separates magnetic and non-magnetic fractions
5. Self-cleaning belt removes collected ferrous contaminants

Ideal Applications:

• Feldspar/quartz purification (Fe₂O₃ reduction to <0.05%)
• Heavy mineral sands concentration (ilmenite, garnet, monazite)
• Scrap metal recovery from industrial byproducts

Limitations: Not suitable for ultrafine particles (<75 micron) without air classification pre-treatment
