Red mud – addressing the problem – Aluminium Insider

Nov 15, 2016In 1965, a cement plant was built to re process residue from Shandong Alumina and by the late 1990s over 6 million tonnes of residue were used to make OPC and oil well cements. However, new standards for cement were introduced that restricted sodium level content and the move to imported bauxite led to a reduction in the amount used for cement.

Some plants reduce aeration to reduce nitrification or add soda ash, lime or magnesium hydroxide as a source of alkalinity if this becomes a problem. The use of lower dissolved oxygen concentration (1.0 mg/L or less) to control nitrification is not without the risk of inducing filamentous bulking by low dissolved oxygen filaments.
