Copper Slag Description

Copper slag particles on microscope
Copper slag particles, as seen on a microscope
(Prem & Verna, 2018)
  • Copper slag is a byproduct obtained during smelting and refining of copper ore rich in sulphides and oxides of iron and copper, in the course of removing iron as iron silicate. During the smelting process at 1250°C, copper liquid settles down due to higher density while copper slag remain on the surface in the segregated state. The copper slag is then collected and cooled with jets of pressurised water. The associated thermal shock creates a unique, glassy amorphous granulate. During the manufacture of the abrasive no crushing or grinding procedures are included. Therefore, the single abrasive particle is not broken up and retains its extreme hardness and tenacity which is the case for all particle sizes. Further, to obtain maximum blasting operating results, the particles are washed multiple times and carefully screened on different grain sizes.
  • Due to its special features, copper slag is recognized for increased blasting efficiency and reaches a maximum potential in cleaning surfaces and material savings.
    • Cleaning Efficiency. Particle density and velocity are the two major contributors in determining the efficiency of an abrasive material. The angularity of the GritSablare grains allows the material to gain greater energy from the nozzle, resulting in extremely high velocity, whilst the particles’ high specific density delivers optimum cleaning power to the surface. Consequently, GritSablare provides powerful fast cleaning and an optimum prepared surface for any coating system.
    • Lower Consumption. In addition to its cleaning efficiency, the consumption of an abrasive also depends on its ability to remove the old coating whilst at the same time producing a satisfactory surface profile. The best surfaces are created by abrasives with a mixture of particle sizes. With GritSablare, particle size distribution is optimised to ensure the best performance which means a notably lower consumption. Particle size distribution is controlled at the production facility with rigid adherence to specified grain sizes.

Copper Slag Applications

Blasting Agent
Blasting Agent
Physical and chemical properties recommend this material as one of the most effective blasting agents, being used on almost any type of surface, both indoor and outdoor. The material allows for fast cleaning applications and material savings as the product can be reused several times.

Cement manufacturing
Composite Cements Additive
Cement is manufactured by decomposing raw materials (including lime stone decarbonation) into calcium, iron and aluminum oxides, which are then remineralized as clinker in a complex and energy-consuming process. Copper slag is successfully used for partial clinker replacement (up to 25%) in the composite cements manufacturing, resulting in cement with different strength and durability features.

Concrete and Mortar Additive
Concrete and Mortar Additive
Copper slag is successfully used as partial replacement for river sand used in concrete and mortar production. Concrete and reinforced concrete are more resistant and durable over time when adding copper slag, being recommended in bridges pillars manufacturing, building blocks, construction etc.

Warm Asphalt Mixtures
Warm Asphalt Mixtures
Copper slag is used to produce warm asphalt mixtures. Copper slag's high hardness provide anti-slippery properties to roads and resistance in time.

Roof tiles
Roof tiles with granular particles
Copper slag allows no water absorption, being a recommended product for manufacturing roof tiles with granular particles, providing superior resistance for roofs.

Other Application
Other Application:
  • Granular replacement for different mixtures;
  • Colorant additive;
  • Anti-slippery material;
  • Underground Mine Backfilling.

User Safety Copper Slag

The substance is not classified as hazardous under the CLP Regulation (1272/2008/EC), is not persistent bio-accumulative and toxic (PBT) or very persistent and very bio-accumulative (vPvB) as defined in Annex XIII of the REACH Regulation, and is not included in the ECHA candidate list of substances of very high concern.

Exposure controls: Risk management measures aimed at the protection of human health are to be considered in cases of inhalation of powder or dusts during use. Process enclosures, local exhaust ventilation or other engineering controls should be employed to keep worker exposure to airborne contaminants below any recommended or statutory limits.

Personal protective equipment: Wear suitable protective clothing.

Hand protection: Wear suitable gloves. Where necessary, gauntlets should be worn to protect against abrasive ricochet.

Respiratory protection: Use properly fitted respiratory protection, complying with an approved standard, appropriate for the known or anticipated exposure levels and the hazards of the product. Blasters should wear an air-fed blasting helmet complying with approved standards, to afford the correct level of respiratory and eye/face protection.

Eye/face protection: Safety eyewear complying with an approved standard should be used when a risk assessment indicates this is necessary to avoid exposure to dusts. If operating conditions cause high dust concentrations wear dust goggles.

Hygiene measures: Handle in accordance with good industrial hygiene and safety practices. Wash hands, forearms and face thoroughly before eating or smoking and at the end of the working period. Routinely wash work clothing and protective equipment to remove contaminants.

Environmental exposure controls: Emissions from ventilation or work process equipment should be checked to ensure they comply with the requirements of the environmental protection legislation.
