Abstract
A process for the simultaneous and continuous removal of arsenic and non-ferrous metals that form chlorides susceptible to volatilization, from materials that contain them, such as roasting residues of pyrites, oxidic iron minerals, metallurgical intermediates and the like, in chopped form, in the form of granules, briquettes and the like by heating and chlorination by means of elemental chlorine-containing gases in countercurrent at temperatures above 800º C, as well as subsequent cooling of the chlorinated product in the shaft furnace, entering the furnace of tub, the hot gases necessary for the heating of the reaction product separately from the chlorination gases and at a height of the shaft furnace in which the elemental chlorine content of the chlorination gases carried upwards has essentially been consumed and the gases and resulting metal chlorides in the chlorination inside the furnace of cu ba are aspirated directly from the chlorination zone into the preheating zone, and are removed from the top of the vat furnace together with the heating gases, characterized in that carbon and/or sulfur are combined in the chopped material. , as solid reducing agents, the heating zone of the shaft furnace is regulated to be weakly oxidizing and the chlorination zone to be oxidizing.
