Sand Blasting

Product Details:

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.

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

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

• 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.

• Asphalt and Road Base Material:

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

  • Offers good skid resistance and load-bearing capacity.

• 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.

• Surface prep and maintenance via grit blasting.

• Used in anti-corrosion treatments and refurbishment.

• Iron Extraction:

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

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

• 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)

Copper Slag

Here's a comprehensive overview of the uses and applications of copper slag across various industries:

• Use: As a partial replacement for sand or cement.

• Benefits: Enhances compressive strength, reduces water absorption, increases durability.

• Replacement Range: Typically 20–50% of fine aggregates.

• Base/Sub-base material: Provides excellent load-bearing properties.

• Asphalt mix: Improves skid resistance and life span of roads.

• Used in manufacturing non-load-bearing blocks, bricks, and tiles.

• Improves density and resistance to wear and weathering.

• Acts as a pozzolanic material or minor additive in Portland cement.

• Reduces clinker usage and lowers carbon footprint.

• Tiles & Ceramic Components: As an additive for high-strength ceramic tiles.

• Decorative aggregates: For landscaping and architectural finishes.

• Most common use worldwide.

• Used for:

  • Cleaning metal surfaces.

  • Removing paint, rust, and scale.

  • Surface profiling before coatings.

• Advantages:

  • Hard, angular particles.

  • Low dust emission compared to silica sand.

  • Reusable and cost-effective.

• Fills low-lying areas, construction of embankments.

• Stable, inert material that does not degrade easily.

• Improves strength and bearing capacity of weak soils.

• Used in geotechnical engineering and backfills.

• Can be used in filters to remove heavy metals or phosphates from industrial effluents (experimental/research level).

• Finely ground copper slag used in asphalt roofing shingles.

• Adds strength, UV resistance, and fire resistance.

• Used as a fluxing agent in metal refining and smelting processes.

• Helps remove impurities from molten metals.

• Always conduct TCLP (Toxicity Characteristic Leaching Procedure) tests before environmental or structural use.

• Quality depends on source of slag and smelting process.

• Proper grading and processing enhance its usability.
