Tailings-to-Bricks Solution: Efficient Utilization of Mining Solid Waste to Create a New Industry of Green Building Materials

Opening a new era of tailings resource utilization

Under the background of sustainable development of mining industry and increasingly strict environmental protection requirements, comprehensive utilization of tailings has become an inevitable choice for the transformation and upgrading of mining enterprises. With advanced tailings activation technology and mature brick-making technology, we provide complete tailings brick-making solutions to realize the perfect transformation of mining waste into high value-added building materials, and help mining enterprises in green transformation and sustainable development.

Core Technology Advantages

Internationally leading tailings activation technology

Adopting German special activator and process formula, effectively stimulate the activity of tailings, so that its dosage in building materials can be up to 60-80%, significantly reducing the amount of cement and improving product performance.

Intelligent Brick Making Production Line

• Fully-automatic batching system, accurately control the proportion of tailings mixing

• Intelligent moisture adjustment technology, adapting to tailings with different moisture content.

• Online quality monitoring system ensures stable product quality

• Intelligent energy consumption management system reduces production and operation costs

Diversified product selection

Main Product Series

• Lightweight heat-insulating bricks: dry density 600-900kg/m³, thermal conductivity 0.15-0.25W/(m-K).

• High-strength pavement bricks: compressive strength of more than 20MPa, excellent wear-resistant performance

• Environmentally friendly permeable bricks: water permeability coefficient ≥1.0×10-²cm/s, preferred for sponge cities.

• Decorative cultural bricks: retaining the natural color of minerals, unique decorative effect.

Product performance characteristics

• High utilization rate of solid waste: 60-80% of tailings mixing, consuming a large amount of solid waste.

• Excellent mechanical properties: compressive and flexural strength reaches the national standard.

• Good durability: frost resistance and weather resistance have passed strict tests.

• Green environmental protection: no radioactive hazards, environmental protection indexes meet the standards.

Production process
