Harsco Metals & Minerals

Harsco Metals sells 10 million tons annually of steel aggregates in18 countries, thereby reducing landfilling of slag and quarrying of natural aggregates. Our approach is to develop aggregate solutions entirely adapted to local market conditions. Harsco Metals processes and recycles a range of steelmaking slags, including BOS Slag, EAF Slag, AOD Slag, and Ladle Slags. The processing reflects:

  • National or State Regulations specifying physical and mechanical properties of materials to be used
  • Additional Product requirements: expected service life, user preferences etc.
