It is established in [4, 5] that in liquid-phase melting processes of reduction and melting of pellets proceed in solid-liquid phase of the foamed slag. Intensive mixing of solid-liquid phase in melting stipulates significant increase of the rate of proceeding heat and mass exchange processes.
In this case oxidation-reduction processes are combined and proceed in solid-liquid phase of the foamed slag, which exerts significant influence on behavior of the phases, in particular of phosphorus.
