Through dust removal, sewage treatment, intelligent management and control, and green mining technologies, combined with policy support and technological innovation, mining companies have achieved “reduction, resource utilization, and harmlessness” of tailings, significantly reducing the environmental burden and promoting the construction of green mines.

Dust and sewage treatment

○ Dust removal equipment: bag dust collector, wet dust removal system (crushing and screening links);

○ Wastewater treatment: sedimentation tank + filtration equipment (recover wastewater from the dehydration process for recycling).

2. Intelligent management and control:

○ Automated control system: real-time monitoring of equipment operation, concentration, and water volume, optimizing process parameters, and reducing energy consumption.

3. Green mining technology:

○ Source reduction: Optimize mineral processing technology and reduce tailings production;

○ Energy-saving equipment: Use low-energy crushing equipment (such as hydraulic cone crusher) and high-efficiency dehydration equipment (such as ceramic filter).

Policy and Technological Innovation Driven

● Policy support: The state encourages the comprehensive utilization of tailings, provides tax incentives and financial subsidies, and promotes enterprises to adopt environmental protection technologies.

● Technology research and development: Promote new equipment (such as third-generation dehydration equipment) and process combinations to solve the problem of fine-particle dehydration and reduce processing costs.

Core Equipment Summary

1. Dehydration equipment: dehydration vibrating screen, chamber filter press, ceramic filter, belt filter.

2. Crushing and sorting equipment: jaw crusher, cone crusher, magnetic separator, flotation machine.

3. Resource-based equipment: vertical mill, brick press, kiln.

4. Environmental protection auxiliary equipment: thickener, dust removal equipment, sewage treatment system.

By adopting these treatment methods and equipment, mining companies can achieve tailings reduction, resource utilization, and harmlessness, conserving resources while significantly reducing the environmental burden and meeting the requirements of green mine development. Specific solutions should be tailored to the tailings’ properties (particle size, composition), processing volume, and environmental standards.
