A mathematical model of mass-transfer processes in off-furnace 
degassing of metal in blasting by inert gas bubbles has been developed. 
The model allows for the effect of both the concentration of molten 
surfactants and the modes of floating of gas bubbles in the liquid 
bath on mass transfer and describes a wide class of mass-transfer 
processes in technologies, which differ in kind and composition of 
metals. The factor of resources and energy saving is determined.
