Abstract
A TiCl.sub.4 gas is supplied to a molten CaCl.sub.2 liquid held in a reactor vessel 6 through a raw material feed pipe 11, TiCl.sub.4 is reduced to produce granular metallic Ti by Ca melted in the CaCl.sub.2 liquid. The molten CaCl.sub.2 liquid in which Ti granules taken out downward from the reactor vessel 6 is mixed is delivered to a separation process 12, the molten CaCl.sub.2 liquid is heated in a heating vessel 15, and separation is generated by a difference in specific gravity, whereby the molten CaCl.sub.2 liquid 16 is located in an upper layer while a metallic Ti 17 is located in a lower layer. The metallic Ti 17 in the lower layer is taken out from a high-melting-point metal discharge port 18, and the metallic Ti 17 is solidified to yield an ingot. The molten CaCl.sub.2 liquid 16 in the upper layer is delivered to an electrolysis process 13 along with the molten CaCl.sub.2 liquid taken out from the reactor vessel 6, and Ca generated by the electrolysis and CaCl.sub.2 are returned into the reactor vessel 6. A separation and recovery method of the invention is applied to the separation process 12 in the above production process, and high-quality Ti or Ti alloy is efficiently separated and recovered from the CaCl.sub.2-containing molten salt with a small amount of energies.
