摘要： When an alkali such as an alkali metal bicarbonate or carbonate is intimately mixed with bauxite or other alumina-containing raw material at an Al.sub.2 O.sub.3 /Na.sub.2 O molar ratio of from 1/1 to 1/3 and the mixture is molded into granules, then calcined and extracted with an aqueous medium, the alumina component can be recovered in a high yield in the form of an aqueous solution of an alkali metal aluminate. The alkali component is not substantially contained in the residue left after recovery of this aqueous solution.

摘要： A method of treating raw materials containing components of metals of the group IVb of the Periodic Table, which comprises heat-treating a raw material of a component of a metal of the group IVb of the Periodic Table containing coloring poisonous metal components such as Mn, V and Cr components in the presence of a flux composed mainly of an alkali metal nitrate or an alkali metal peroxide which is a thermal decomposition product of the alkali metal nitrate in an amount 2 to 5 times the amount of the raw material on the weight basis in a non-reducing atmosphere to thereby effect fluxing reaction, and subjecting the resulting fluxing reaction product to a leaching treatment of at least one stage in an aqueous medium to separate the fluxing reaction product into said coloring metal components and a concentrate of the component of the group IVb of the Periodic Table which is acid-soluble and substantially free of said coloring poisonous metal components. In practising this treating method, if a residue left after the above leaching step is incorporated into a mixture of the raw material and the flux, the composition is granulated and the granulated composition is heat-treated, the fluxing reaction of the raw material can be accomplished while keeping the granulated composition in the substantially non-sticky granular state throughout the fluxing heat treatment.
