The thermophysical properties of Kachkanar titanomagnetite pellets of different basicity are determined. By mixing, the dependence of the mean physical specific heat of the pellets on the temperature and phase composition is found. The apparent specific heat of the pellets is determined by means of a gravimetric system with continuous recording of the change in pellet mass. By establishing an oxidative or neutral atmosphere, it is possible to distinguish between oxidation and decarbonization. The thermal diffusivity of the pellets is determined by means of a quasi-steady method, which permits the use of simple formulas in continuous heating. The thermal conductivity of the pellets is found from an equation relating their density, specific heat, and thermal diffusivity. The results are of great interest and may be used in the design of new roasting systems and also in optimization of the operational parameters of existing systems.
