Red mud as a construction material by using bioremediation

hydroxide. Red mud generation is depending upon the type of bauxite used in industry. About 1.2-1.4 tons of red mud is generated per each ton of alumina produced. Each year, more or less 75 million tonnes of red mud is produced worldwide. The iron compounds present in it confers the red colour to it and hence it is called red mud.
