Magnesia recycled materials

LKAB Minerals offer a portfolio of magnesia based recycled refractory materials, sourced and processed at our own sites in the UK and Netherlands.

LKAB Minerals offer a range of magnesia recycled refractories materials

The process of recycling refractory materials involves sorting to remove contamination either at the site of origin or at one of our own sites 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.

Recycled refractory materials processing services

LKAB Minerals offer a service of layering, blending and mixing of raw materials to specific customer recipes. Additionally, LKAB Minerals offer a facility of processing customer owned material to specific requirements. Read more about it here.

Recycled refractory materials uses


Our range of magnesia 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.

Metallurgical additives

Our magnesia based recycled refractory materials are suitable as additives for slag conditioning applications. Additionally, the slag conditioning mix can be processed at our own toll manufacturing site.

  1. Fused Alumina
    • Alumina (also known as Corundum or Aluminium Oxide) is the family name for inorganic compounds with the chemical formula Al2O3. Fused Alumina is made in electric arc furnace by passing a current between vertical carbon electrodes. The heat generated from this procedure melts the alumina feedstock.

  8. Refractory grade Magnesite
    • Magnesite is a natural ore identified as a magnesium carbonate, occurring as a primary mineral in igneous and sedimentary rocks. The magnesite ore is mined and classified; this material is then purified and calcined to provide the raw material for refractory grade magnesite products.
