The process of recycling refractory materials involves sorting to remove contamination before being primary crushed and dried. Material is then processed to individual customer specifications. Chemical analysis is carried out on at each stage of the process to ensure consistency.

Alumina materials applications

  • Alumina recycled materials in refractories

    Our range of alumina recycled materials are used in a number of applications including as a full or partial replacement to virgin materials in monolithic and shaped refractories. Our recycled materials are a cost efficient alternative to virgin materials.

  • high friction road surfacing

    Alumina recycled materials for high friction surfacing

    Our Alumina based recycled materials can be used in low traffic area high friction surfacing applications. Read more about this specific topic here.

  • Steel Ladle with slag forming at top

    Alumina recycled materials as metallurgical additives
