ECCO-SALT Salt slag recycling (recovery of black dross)

The salt slags recycling process is based on THREE objectives:

  • COMPLETE SEPARATION OF COMPOUNDS:
    • Metallic Aluminium
    • Salt (mix of sodium and potassium chloride)
    • Oxides
  • INERTIZATION of the reactive compounds:
    • Forcing the reaction of them in a controlled manner
    • Elimination of gases generated by incineration
  • VALORIZATION of the products obtained
    • Both metallic aluminum and salt return as products to the refinery
    • Metal oxides are treated to reduce the chloride content so that they are suitable for commercialization and therefore be considered as a product

Thus, from a DANGEROUS WASTE we get three VALORIZABLE PRODUCTS
