A method for producing fluxed pelletized iron-ore material comprises separate dosing of components into the two blends comprising: iron-ore concentrate, flux, low-melting or refractory compounds, solid and liquid fuel, linking additive, and mixing them to obtain from each blend of raw pellets with low and high melting point, mixing these raw pellets, loaded into the calcined aggregate with subsequent heat treatment, comprising the drying, heating, the high-temperature annealing and cooling. The equal ratio of CaO/SiOis maintained in the both batches for producing raw fluxed pellets with low and high melting temperature. Iron-ore concentrate, low-melting compounds, carbon in the solid or liquid fuel are introduced into the batch to produce raw pellets with low melting temperature. Iron-ore concentrate, refractory oxides are introduced into the batch to produce raw pellets with a high melting temperature.
