Magnetite ore, a key iron-bearing mineral, requires specialized crushing and processing to maximize industrial value. Here’s an optimized workflow to ensure efficiency and quality:
1. Crushing Stage
Primary Crushing: Large magnetite ore blocks (≤1,200mm) are reduced to 200-300mm using jaw crushers or gyratory crushers. This step ensures uniform particle size for downstream processing.
Secondary Crushing: Cone crushers further break down ore to 50-100mm, enhancing liberation of magnetite from gangue minerals.
2. Grinding & Magnetic Separation
Ball Milling: Ore is ground to 0.074-0.4mm to fully liberate magnetite particles.
Magnetic Separation: High-intensity magnetic separators extract magnetite from non-magnetic impurities, achieving >95% recovery rates.
3. Dewatering & Tailings Management
Thickening & Filtration: Concentrates are dewatered via thickeners and vacuum filters to reduce moisture content (<10%).
Eco-Friendly Tailings: Dry stacking technology minimizes environmental impact.
Optimization Tips for Higher Efficiency
Energy-Saving Equipment: Adopt HPGR (High-Pressure Grinding Rolls) to reduce power consumption by 20-30%2.
Automation Systems: Real-time monitoring ensures stable processing parameters and minimizes downtime.
By integrating advanced equipment and eco-conscious practices, magnetite ore processing can achieve both economic and environmental sustainability.
