Catalyzing Commercialization: An Economically Viable Process …
For every ton of aluminum produced from bauxite, nearly 2.5–4 tons of red mud is produced. Since the advent of the Bayer process in the late 1800s, over 3 billion tons of red mud have been accumulated and stored in red mud ponds. The production of red mud, which recently reached 130 million tons per year, is expected to grow annually by about 6%.
