The chlorination of metal-bearing materials, e.g., titaniferous ores, to produce metal halides, e.g., titanium tetrachloride, in a fluidized bed maintained in a cylindrical-type furnace is described. Fluidizing and chlorinating gas is introduced into the furnace through gas distributor means having a single vertical gas exit opening, at least one principal linear dimension thereof measured across the opening being no greater than seven thirty-seconds inch. In a preferred embodiment, the gas exit opening has a cross-sectional area at the point of gas discharge of from about 0.00019 inch2 to about 0.038 inch2.
