Re‐using bauxite residues: benefits beyond (critical raw) material

Bauxite residues from alumina production are available at a multi‐million tonnes scale worldwide. So far, attempts have been made to find alternative re‐use applications for bauxite residues, for instance in cement / pig iron production. However, bauxite residues also constitute an untapped secondary source of CRMs.

Red mud is piling up. Can scientists figure out what to do with it?

Aluminum is one of the most commonly recycled materials, with 75% of all aluminum ever produced still in use. But there is an ever-burgeoning demand. Aluminum production starts with mining bauxite, a rock rich in aluminum oxide that also contains a wealth of other elements, including silicon, iron, and titanium.

What Is Bauxite Used For? Everything Explained

Bauxite Is Used For Cement Production. Mixing bauxite into cement improves its overall qualities and makes it more resistant to water damage. The calcium carbonate contained in bauxite is what gives cement its strength and durability, allowing it to withstand exposure to moisture better than standard cement can.
