Abstract
Red mud is described as a major industrial waste produced by the Bayer process for the extraction of alumina from bauxite ores. The Red mud was collected from Bukit Goh and it physical, chemical and mineralogical composition were investigated in terms of it environmental effects. Because red mud has a lot of hazardous effect on man and his environment, it intrinsic properties are characterised by high alkaline, extremely saline, sodic and high heavy metals content. The pH, EC, Heavy Metals and Mineral contents were analysed using pH meter, EC meter, ICPOES and XRD respectively. The results show that, pH, EC and Heavy metals concentration of red mud decreased with increasing storage time and Fe, Cd, As and Pb concentration were determined. In general, the newly collected red mud retained more heavy metals than the old red muds.
