The process of recycling refractory materials involves sorting to remove contamination before being primary crushed and dried. After this, we process the material to individual customer specifications. We make sure that we carry out chemical analysis at each stage of the process to ensure consistency.
To make this more visible we have two videos available that explain our work with these materials in short:

Alumina recycled materials standard grades
- 5-8mm (-8+5mm)
- 3-5mm (-5+3mm)
- 1-3mm (-3+1mm)

Alumina recycled materials origins
LKAB Minerals recycled materials originate predominantly from steel and cement works. Together with a partner company we recover, sort and process the material in the UK.
Alumina recycled materials toxicology
Our range of alumina recycled materials is non-toxic, non-hazardous stable minerals. You can download the Safety Data Sheets from the documents tab.
