PRODUCTION OF IRON(II) SULPHATE(FeSO4.7H2 O) FROM RED-MUD

Abstract

The red-mud obtained during the production of aluminium from bauxite as a by-product contains valuable materials such as Fe, Al, Na,V, Ti etc. In this study, red-mud was dissolved with H2 SO4 and converted to FeSO4.7H2 O by 86 % efficiency. The optimum converting conditions were found as heating for three hours at 170o C. The red-mud is not suitable for the production of pig iron because, it hasn't got enough iron contents(38.57 per cent Fe2 O3). We concluded that, the red-mud can be used in production of FeSO4.7H2 O.
