Abstract

<PICT:0379855/III/1> Zinc white is obtained by vaporizing zinc or other metallic zinc-containing metal in one region directly by means of hot gases which contain no constituents such as oxygen or carbon dioxide which would react with the zinc, the zinc vapour being thereafter carried over to the oxidation region. Reference is made to the use of suitably purified gases from generator, roasting and oil furnaces. The gases may be passed over or through the metal, which, in the former event, may be covered with anthracite or coke. Metallic bye-products are removed from the vaporization region for further treatment. A furnace shown in the Figure comprises a coke-filled shaft 1, the upper end of which is provided with an adjustable perforated disc 5 through which air is admitted. The combustion gases pass through a layer of coke 12 provided in the rotary drum 8 over the zinc contained therein. The zinc vapours are burned in chamber 13, air-inlet apertures 15 being provided for this purpose. The bath is replenished by feeding zinc into the conduit 18, the metal being melted by the heat of combustion of the zinc. In a modified apparatus, the rotary drum 8 is not present, the metal from conduit 18 falling on to the top of a column of burning coke contained in vertical shaft furnace, up through which air is passed.
