FIELD: methods of reclamation of wastes. SUBSTANCE: starting reaction mixture is directed to reactor containing melt bath to subject reaction mixture even partially to chemical reaction for forming an intermediate component. Part of intermediate component is mixed with waste gas escaping from melt bath. Then at least part of intermediate component is separated from waste gas and is returned to melt bath, after which returned intermediate component is converted to its monatomic components which are later react with other components of bath for forming compounds which are stable in operation of device, thus making it possible to control reaction of starting reaction mixture. EFFECT: reliable control of chemical reaction. 14 cl, 1 dwg
