- Аннотация: A thermodynamic calculation of the possibility of mass transfer of metal compounds in conditions of filtration combustion of metal-containing mixtures was carried out. According to the results the metals were divided into two groups: the fi rst group includes metals that form both condensed and gaseous phases, and the second group includes metals that are only in the condensed phase. Under conditions of fi ltration combustion wave due to continuous evaporation and condensation, it is possible to organize mass transfer of compounds of the fi rst group metals in order to concentrate them in a specifi c zone of the reactor. Metals of the second group do not participate in mass transfer under the conditions of a fi ltration combustion wave and will remain in solid combustion products (in ash). Their concentration is possible only if there is a large amount of a combustible component in the initial mixture. In this case, due to the burnout of the combustible part and the preservation of metal compounds in the ash residue, their concentration will occur. Concentration of metals will allow performing their further economically justifi ed recovery by traditional methods.
