Din, supervisor Civil engineering Also available in printed version Bauxite is the primary ore for aluminium extraction. It is treated with sodium hydroxide at above 250oC to extract alumina in the Bayer’s process. Iron, together with impurities that are insoluble in the caustic solution, will be removed by clarification. The residue generated after clarification is known as Bauxite Residue (or Red Mud). Red Mud (Bauxite Residue) is the main waste product of the alkaline extraction of alumina from bauxite with high amounts of heavy metals. These heavy metals cause risks to human health, plants, animals, ecosystems, or other media as most environmental contamination and human exposure result from anthropogenic activities such as mining and smelting operations, industrial production and domestic and agricultural use of metals and metal-containing compounds. This review focuses on removing these heavy metals (As, Ni, Cr and Fe) from bauxite residue using gracilaria sp. In achieving the removal efficiency of heavy metals from Bauxite Residue, the study was performed in three separate phases. In Phase I, the experimental work involves the characterisation of Bauxite Residue in relation to its heavy metals, pH value and Electrical conductivity. In this phase also, an overview on seaweed with special reference to gracilaria sp was analysed. In Phase II, alginate beads were produced using gracilaria sp through oil spherification method. This phase was followed by the treatment of Red Mud using the produced beads in phase II. In this phase (III), Inductively Coupled Plasma Optical Emission Spectrophotometer (ICPOES) determined the heavy metals removal efficiency before and after the application of alginate beads as an adsorbent. Results of extraction of heavy metals from Bauxite Residue showed that gracilaria sp adsorbents were effective and efficient in removing fractions of Cr, As, Ni and Fe at 1g, 2g and 3g. However, the extractions were found effective and efficient at various alginate beads concentrations (1g, 2g and 3g) zulaihi UTM 128 p.
