Abstract: 1,125,546. Caustic Magnesia. HARBISONWALKER REFRACTORIES CO. 19 May, 1967 [20 June, 1966], No. 23309/67. Heading C1A. Caustic magnesia is produced by burning water-wet magnesium hydroxide filter cake in a furnace in which the magnesia dust carried over from the burning is removed from the flue gases and combined dry with the filter cake to form a paste having a solids content from 60 to 80% by weight, the paste being fed to the furnace. The furnace may be of the multiple hearth type, with a burner located only at the central hearth or hearths, in which the temperature of the filter cake is raised to 1800‹ to 2000‹ F., magnesia dust being recovered from the flue gases by a dry precipitation process. Some of the magnesia may be fed direct to the central hearth or hearths of the furnace.
