Abstract

Disclosed are a method and an apparatus for concentrating a Ti powder in a CaCl2-containing molten material, particularly in a CaCl2-containing molten material which contains a Ti granule (powder) produced by the Ca reduction of TiCl4. The Ti concentration in a CaCl2-containing molten material which has a Ti powder dispersed therein is increased by liquid cyclone. This method can be suitably applied to the concentration of a Ti powder in a CaCl2-containing molten material which contains a Ti powder produced by the Ca reduction of TiCl4. The liquid cyclone may be one having a trunk part (9) with a diameter (Dc) of 40 to 300 mm and a length (L) of 0.5 to 8 times the diameter. By using this type of liquid cyclone, the Ti concentration in a molten salt can be increased at a good collection rate. This concentration method can be achieved readily by using the concentration apparatus according to the invention.
