Project Overview
A Mongolian iron ore beneficiation study revealed an ore grade of 36.65% Fe, with 81.77% of iron existing as magnetite (FeO)
1. This high magnetite content makes the ore ideal for dry magnetic separation, aligning with Mongolia’s arid conditions and water scarcity. The project adopts a three-stage, closed-circuit crushing process integrated with pre-concentration technology to maximize efficiency and minimize energy consumption
Equipment Configuration
- Primary Crushing (Jaw Crusher):
- Model: PE1200×1500 or similar large-scale jaw crusher.
- Role: Processes raw ore (≤1000mm) into ≤250mm particles for secondary crushing3
.
- Secondary/Tertiary Crushing (Cone Crushers):
- Models: HST250S2/HST250H2 or SMH350 hydraulic cone crushers.
- Advantages: Layer-crushing principle reduces product size to ≤15mm while maintaining high throughput
- Screening & Magnetic Pre-Concentration:
- Vibrating Screens: S5X3075/S5X1845-2 for closed-circuit grading
- Dry Magnetic Separators: CTF1030 units remove waste rock early, cutting grinding costs by 30%
- Automation & Dust Control:
- Centralized PLC system monitors real-time performance
- Pulse bag dust collectors ensure >98% dust recovery, meeting Mongolian environmental standards
Process Flow:
Raw ore → Jaw crusher → Cone crushers → Screening → Dry magnetic separation → Final product (0-15mm).
Key Advantages
- High Efficiency: Large-capacity equipment (e.g., 500t/h cone crushers) ensures stable 1000t/h output
.
- Durability: Tungsten carbide liners extend wear life in abrasive ore conditions
- Water-Free Design: Dry magnetic separation suits Mongolia’s arid climate
- Smart Operation: Remote monitoring reduces labor intensity and downtime
Client Feedback
“The line’s stability exceeded expectations—profit margins rose by 15% post-installation. Supplier technicians even resolved midnight breakdowns onsite, ensuring zero production delays.”
Technical Highlights
- Resource Utilization: Tailings repurposed for cement/road materials
- Local Adaptation: Equipment withstands Mongolia’s -30°C winters with minimal insulation
