Abstract
In a process for obtaining zinc oxide by burning a pulverulent mixture of zinciferous originating material with carboniferous fuel such as coal dust in burners of the coal dust type and precipitating the oxide from the cooled effluent gases, originating materials containing zinc sulphate, especially flue dust derived from the roasting of zinc ores, are employed, and excess of combustion air is avoided. The effluent gases are cooled by a spray of water, thereby precipitating zinc oxide and oxidizing any metallic zinc present.
