Abstract
A cloud or dispersion of a particulate flux is formed in a combustion zone for the purpose of capturing metallic vapor from the combustion gas by formation of a eutectic of the metal and the flux, as a melt on at least the surfaces of the dispersed flux particles. The flux particles are heated within the combustion zone to a temperature sufficient to form the eutectic melt. The preferred flux particles utilized in the invention include conventional metallurgical fluxes, e.g. calcium carbonate, sodium carbonate and magnesium carbonate.
