Abstract: Titanium dioxide industries produce anatase grade titania through sulphate route by using ilmenite and sulphuric acid as major raw materials. After the reaction, a mixture of ferrous and ferric sulphate is produced as an industrial effluent. The disposal of this effluent is a major problem for all mineral processing industries. Generally, these effluents are disposed of into the nearby river or sea causing an environmental issue. In this study, a series of reactions were performed in a research laboratory to find out a method for utilising the above effluent to make a value-added pigment material. The study revealed that the effluent ferrous sulphate can be converted into an anticorrosive pigment called zinc ferrite by co-precipitation. The prepared material is characterised by wet chemical and instrumental analysis methods like FT-IR, XRD, particle size, surface area measurement and SEM-EDX. The pigmentary properties of zinc ferrite prepared are also evaluated for evaluating its use as a pigment material for anticorrosive paints. The study reveals that the ferrous sulphate industrial effluent from ilmenite processing can be successfully converted to a value-added pigment product called zinc ferrite. The details are discussed in this paper.
