The Global Mineral Recovery Company (GMR) has published the commissioning of its commercial demonstration plant for the recovery of bauxite residues on the site of Rio Tinto’s Vaudreuil Alumina plant. The USD9m project was initiated in 2017. GMR has designed a pyrometallurgical technology to treat and recover the bauxite residues from the production of alumina. This process transforms and extracts specific compounds from the residue, making it useful in certain building material applications.
