about us - Harsco

Steel slag is a post-metallurgical waste, consisting of 4% – 11% of metallic constituents, which following the recovery may be reused as input scrap in the steelmaking process. Delivery of the steel slag to the slag processing line initiates the process of separation of magnetic materials (scrap) and non-magnetic (aggregates).
