Mining activities, while essential, can often result in environmental and health challenges. Tackling one such significant issue, the Eidsvold Siltstone Metakaolin Programme has embarked on an ambitious journey to transform waste slurry into metakaolin. The implications of this are profound. By converting slurry into metakaolin, they aim to contain hazardous heavy metals in mine tailings dams, thereby safeguarding ecosystems. Further, by reducing the risk factors, the programme ardently hopes to decrease the instances of coal miners contracting the dreaded black lung disease.
