Red mud is a solid waste which is generated in the process of alumina production and is of highly alkaline. Red mud has very complex compositions but contains a variety of rare and valuable metals. In addition, its high alkalinity is a severe pollution to water, land, air and environment, which has been one of the main factors to affect the sustainable development of aluminum industry. Bayer Red mud which is a waste by product of Aluminum extraction process is dumped in large areas near the sea or nearby ponds. Bayer Red mud is dumped after the neutralization process. Neutralization is done by mechanics of seawater treatment. The mud is actively mixed with the seawater for a period of around 30 minutes to enable the reactions to take place. Clay content had significant effect on permeability, hardness or GCS while moisture content had a little effect. Through this project an attempt is made to carry out different experiments by making red mud a constituent in mold sand in different proportions and to manufacture castings and compare the resulting casting with regular casted component. Taguchi's process is used to optimize the process parameters which come into account in the experiments..
