The recovery with sulfuric acid leaching of Ti content of red mud, a waste of Turkey Etibank Seydisehir Aluminium Plants, has been studied by statistically designed experiments. The effects of relevant factors, such as temperature, leaching time, acid normality, solid-to-liquid ratio, stirring rate, on leaching yield of TiO2 have been investigated. Experiments have been planned by factorial design and orthogonal central composite design methods. A model has been obtained by means of variance analysis at the 92.5% confidence level.
