  • Method for production of iron ioxide pigments
    Patent number: 6818052
    Abstract: The invention provides a process for the production of iron based pigments and anticorrosive additives from elemental iron comprising: a) reacting iron Fe° with ferric sulphate Fe2(SO4)3 and with sulfuric acid H2SO4 to produce ferrous sulphate FeSO4; b) oxidizing ferrous sulphate FeSO4 in a bacterial solution containing at 107 bactrial cells of thiobacillus ferrooxidans per 1 ml of solution under aerobic conditions to produce ferric oxide sulphate Fe2(SO4)3; c) reacting said ferric oxide sulphate Fe2(SO4)3 with water, to precipitate iron oxide monohydrate Fe2O3×H2O; and d) re-cycling the solution from step c, to step a, to utilize the sulphuric acid and a portion of the ferruos sulphate values therein.
