摘要: The invention relates to a process for removing tin, arsenic and antimony from molten lead by means of oxygen or oxygen-containing gas mixtures, which is or are blown into the molten lead by means of at least one gas nozzle (2). To avoid damage to the gas nozzle, at least the oxygen outlet region (13) thereof, located in the molten lead (6), is enveloped by an inert gas.
