REDUCTION OF THE ADZHINAUR TITANOMAGNETITE CONCENTRATES OF AZERBAIJAN BY NATURAL GAS FOR THE PRODUCTION OF IRON POWDER AND TITANIUM DIOXIDE
Based on the theory of granulation of powders in a drum apparatus by using 3D modeling, granules with flux additions of 25% soda with optimum size, humidity, strength and porosity were obtained. It has been revealed that, when using such granules, the reduction reactions of titanomagnetite concentrates proceed in the kinetic-diffusion region, are conjugate: in reducing reactions, CO and H2 are inductors and the CH4 acceptor. The first two reactions initiate the reduction of magnetite to metal. Using chitosan as a bioactive modifier, anatase modification of titanium dioxide was obtained from powders of polytitanic acid xTiO2×yH2O.
