It is a blasting abrasive used for surface preparation. It is basically an “Iron Silicate“and commercially called copper slag since it is derived out of copper concentrates.
Copper slag is a blasting abrasive used for surface preparation. It is basically an “Iron Silicate“and commercially called copper slag since it is derived out of copper concentrates.
Copper slag is generated out of copper concentrate while extracting copper in the copper smelting units. It is composed of Ferro silicate material and oxide when the slag is quenched in the cold water. This process makes the slag into a granule form resulting in coarser and angular particles.
It is used to remove contaminants, paints, rust, etc., and to clean the steel surface.
This material is air blasted from the compressed air through the nozzle to the surface. Material is stored in a blast pot and compressed air passes through hoses to the pot and to the nozzle. The material is propelled along with the compressed air and allowed to hit the surface.
It is used widely in shipyard, steel fabrication, oil and gas, and construction chemicals.

Recycling & Disposal:-
It can be recyclable but it depends on the contaminants and the availability of coarser material after blasting. Generally, it is not recommended but can be used subject to the above at least once again.
It is safe to dispose of along with other waste material since the product does not have a leachable effect. However, it is subject to the local municipality waste disposal procedure.
