Abstract

In a process for the extraction of titanium by the reduction of titanium tetrachloride with sodium, the product mixture of refractory metal and sodium chloride is crushed to pass a 1/4 inch sieve. Fines which pass 100 mesh B.S.S. are removed and form a sodium chloride-rich portion containing up to 10 per cent of titanium; the remaining larger particles contain 70 per cent titanium. Titanium is extracted from the titanium-rich portion by aqueous leaching or vacuum distillation of the sodium chloride impurity and are melting, to produce a massive titanium with a hardness of 120 D.P.N. containing 0.001 per cent of hydrogen. Elutriation, followed by aqueous leaching of the sodium chloride-rich portion, produces titanium which when are melted, has a hardness of 135 D.P.N. and a hydrogen content of 0.003 per cent.
