Key Requirements:
Efficient Dewatering: Reduce moisture content in concentrates/tailings to lower transport and smelting costs.
Energy Efficiency & Eco-Friendliness: Comply with green mining policies, minimize wastewater discharge.
Automation: Adapt to smart, unmanned mining trends.
Industry Trends:
Dry tailings disposal (reducing tailings dam risks).
High recovery rates (improving metal extraction efficiency).
Low energy consumption (cutting operational costs).
2. Product Comparison
Equipment | Best For | Key Advantages | Solves Industry Pain Points |
Vacuum Belt Filter | Coarse tailings, coal washing, high-capacity needs | ✅ Continuous operation ✅ Clog-resistant ✅ Low maintenance | Replaces inefficient, energy-intensive filter presses. |
Ceramic Disc Filter | Fine concentrates (copper, zinc, gold) | ✅ Ultra-low moisture (<15%) ✅ 30% energy savings ✅ Zero contamination | Cloth filters clog easily; high cake moisture. |
Thickener | Tailings concentration, backfill, wastewater settling | ✅ High capacity ✅ Stable sedimentation ✅ Reduces water usage | Traditional settling ponds are space-intensive and inefficient. |
Vertical Press Filter | Ultra-fine slurries (Li-ion materials, Al(OH)₃) | ✅ High-pressure dewatering ✅ Handles sticky materials ✅ Fully automated | Vacuum filters fail for ultrafine particles. |
3. Case Studies
