    • A process of continuous metal refinement comprising feeding molten metal to a reaction chamber, introducing gaseous and solid oxidants, adding bulk materials, fully converting the metal and slag into a foamy emulsion, creating, in the reaction chamber, an increased pulsating pressure and a considerable deviation of a system from thermodynamic equilibrium by way of creating a self-organizing system of chemical reaction with gas evolution and taking off the emulsion into a refining sump at the critical speed of egress of two-phase liquid, separating the metal and slag in said refining sump and withdrawing the gas through a high layer of emulsion at a definite rate. A unit for continuously refining metal, comprising a spherical reaction chamber (1) with a channel (5) for supplying molten metal and a channel (4) for feeding bulk materials, with a device for feeding a gaseous oxygen made in the form of oppositely arranged lances, a cylindrical connection channel (2), a refining sump (3) with tap holes (20, 15) for withdrawing metal and slag, respectively, the slag tap hole is divided into two vertical channels (16, 17) for separating slag and gas, respectively, a channel (13) for the delivery of slag-forming materials, and lances (11, 12) for feeding oxygen.
