A Mineralogical Assessment on Residues after Acidic Leaching of Bauxite Residue (Red Mud) for Titanium Recovery
Due to its alkalinity, red mud produced by the Bayer process may affect both the environment and human health. For this reason, its further utilization instead of disposal is of great importance. Numerous methods have already been studied for hydrometallurgical treatment of red mud, especially for the recovery of various metallic components such as iron, aluminum, titanium or rare earth element...

متن کاملMetal Components (Fe, Al, and Ti) Recovery from Red Mud by Sulfuric Acid Leaching Assisted with Ultrasonic Waves
Abstract—Nowadays the red mud generated from Bayer alumina production process seriously threats the environment and human safety. Therefore, reduction and recycling of red mud is an urgent topic in aluminum industry. In this study, the effects of various parameters, ultrasound power, reaction temperature, leaching time, acid concentration, and solid to liquid ratio on the leaching of Fe, Al, an...
متن کاملPhysical and Chemical Properties of Sintering Red Mud and Bayer Red Mud and the Implications for Beneficial Utilization
Performances of two common types of red mud, Bayer red mud and Sintering red mud, were investigated in this research. Their compositions, mechanical properties and microstructure characterization were measured through XRD, TG and SEM analysis. Their shear strength, particle size, density and hydraulic characteristics also had been performed. Huge differences between the basic mineral types of t...
