In a process for workup of a melt containing iron oxide and phosphorus oxides for recovering elemental phosphorus by direct carbothermic reduction of the phosphorus oxides the melt is atomized and the thus obtained melt droplets in contact with carbon monoxide as a reductant are passed through a direct reduction sector in which the phosphorus oxides present are at least partly reduced to afford gaseous elemental phosphorus and from which the melt droplets together with the gaseous elemental phosphorus are supplied to a separator by means of which the gaseous elemental phosphorus is separated from the melt droplets.
