Alumina commodity Critical Material
Aluminium oxide considered as a refined commercial material, used as feed for aluminium smelting and in nonmetallurgical applications such as ceramics, abrasives and refractories. This commodity is distinct from aluminium metal, aluminium hydroxide, bauxite ore and red mud. The broad commodity does not establish a particular crystalline phase or high-purity product specification. The EU designations explicitly name alumina as the intermediate processing form within the combined bauxite/alumina/aluminium value chain. No microbial mechanism is asserted here.
