MIXING REACTOR OF ATTRITION MILL TYPE AND CHLORIDE PROCESS FOR TANTALUM PRODUCTION USING THE SAME

摘要

An attrition mill type of agitation reactor for chlorination is provided to be employed in tantalum ore refining process which produces tantalum chloride from raw materials likely generating high boiling point chlorides while greatly reducing chlorination temperature sufficient to maintain the chlorides in a solid state, and removes the chlorides from the reacted surface of the tantalum ore. The agitation reactor(100) comprises: an agitation motor(110); an agitation shaft(120) made of alumina material, which has a protective case and plural agitation rods in a radial form, is connected to the motor and rotates dependent on revolution of the motor; a heat diffusion plate(130) for cooling the agitation shaft, which is equipped to the top end of the agitation shaft; a cylindrical reactor(140) which has first inlet duct for flowing seal gas to the top end, an outlet duct for discharging the reaction product, and second inlet duct for putting reaction gas into the reactor at the bottom end of the reactor.
