Solution Proposal for Mining & Metallurgy Pollution Control

1. Major Pollution Sources

The primary pollutants in the mining and metallurgy industry include:

• Mineral dust (generated during excavation, crushing, and transportation)
• Smelting flue gas (containing sulfur oxides, particulate matter, and other hazardous emissions)

2. Proposed Solutions

To mitigate pollution and comply with environmental regulations, we recommend the following integrated solutions:

2.1 Large Wet Scrubbers

• Function: Efficiently captures mineral dust through water spray mechanisms.
• Advantages:
  • High dust removal efficiency (>95%)
  • Low maintenance costs
  • Suitable for high-dust environments

2.2 High-Temperature Flue Gas Treatment System

• Function: Treats smelting flue gases containing sulfur and heavy metals.
• Advantages:
  • Withstands extreme temperatures (>500°C)
  • Reduces SO₂ and NOx emissions effectively

2.3 Desulfurization & Dust Removal Integrated System

• Function: Combines desulfurization (removing sulfur oxides) and dust removal in one process.
• Advantages:
  • Compact design, saving space and energy
  • Lower operational costs compared to separate systems

3. Expected Outcomes

By implementing these solutions, the following improvements are anticipated:

• Dust emissions ≤ 30 mg/m³ (meeting strict environmental standards)
• Extended equipment lifespan (reducing downtime and replacement costs)
• Enhanced workplace safety (reducing workers’ exposure to harmful pollutants)

4. Conclusion

This comprehensive pollution control system ensures efficient, sustainable, and regulatory-compliant operations in the mining and metallurgy sector.
