Abstract
A process for producing metallic titanium includes forming metallic titanium fine particles by supplying liquid or mist titanium tetrachloride from above the surface of a reaction bath liquid containing fused magnesium and fused magnesium chloride in a reaction vessel to effect a reaction, wherein a circulating flow perpendicular to the bath surface of the reaction bath liquid is generated or extended just under the bath surface by imparting a stirring force to the reaction bath liquid so as to generate or increase an upward flow rate of the reaction bath liquid in at least part of the region at a depth of more than 100 mm below the bath surface.
