REDUCTION OF THE ADZHINAUR TITANOMAGNETITE CONCENTRATES OF AZERBAIJAN BY NATURAL GAS FOR THE PRODUCTION OF IRON POWDER AND TITANIUM DIOXIDE
A.N.Mammadov, A.M.Gasimova

 

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.
