Abstract :
This research was carried out to characterize and investigate the use of local clay found in Delta state for the extraction of pure alumina by the use of HCl and H2SO4 acids. In order to ascertain the most suitable conditions, leaching experiments were conducted under several process variables such as varying; clay to acid ratio (5:100 and 10:100), particle size (600?m and 850?m), dissolution temperature (50˚C, 100˚C and 150˚C), calcination temperature (600˚C and 700˚C) and acid concentrations (0.5M, 1M and 2M). Alumina content was determined using FS 240 Varian Atomic Absorption Spectrophotometer (AAS). Minerals contained in the clay were sorted out by using 1.54056-CuKα1 for 2ϴ arranged by X-Ray power Diffraction (XRD) obtained from International Centre for Diffraction Data
