Black Copper Slag

Copper slag is a byproduct of copper smelting, composed mainly of iron, silicates, and other metal oxides. Beyond abrasive blasting, industrial-grade copper slag finds applications across construction, manufacturing, and environmental sectors due to its hardness, density, stability, and chemical properties.

✅ Brief Uses & Applications of Industrial Grade Copper Slag

1. Abrasive Blasting (Primary Use) 

• Used as a substitute for silica sand in grit blasting.

• Removes rust, paint, and scale from metal surfaces for coating prep.

2. Cement and Concrete Industry

• Partial Replacement for Sand or Cement:

  • Enhances strength, durability, and resistance to chemicals.

  • Improves workability and reduces permeability.

• Pozzolanic Properties:

  • Reacts with calcium hydroxide in cement to improve performance.

3. Road Construction

• Asphalt and Road Base Material:

  • Used as aggregate in bituminous pavements and sub-base layers.

  • Offers good skid resistance and load-bearing capacity.

4. Landfilling and Soil Stabilization

• Landfill Liner or Cover Material:

  • Used as a barrier material to contain leachate in waste management.

• Soil Amendment:

  • Improves load-bearing capacity and reduces erosion.

5. Shipbuilding and Offshore Platforms

• Surface prep and maintenance via grit blasting.

• Used in anti-corrosion treatments and refurbishment.

6. Metal Recovery

• Iron Extraction:

  • Residual iron content in slag can be recovered through magnetic separation.

7. Shotcrete and Refractory Applications

• Mixed with other materials for use in fireproof linings, tunnel linings, and high-temperature insulation.

Advantages

• Cost-effective and eco-friendly (waste reuse)

• High hardness (~6–7 Mohs scale)

• Chemically inert and non-toxic

• High specific gravity (suitable for heavy-duty fill)
