Red mud (bauxite residue) an unnecessary problem? #

2019-1-1  Global annual production of red mud (bauxite residue) is about 150 million tonnes. It contains raw materials for the production of iron, silicon and aluminium, and is dumped as waste in spite of the availability of recycling technologiesbauxite residu. This is because it is cheaper to dump bauxite residue as waste and continue mining for new ores.
