Abstract
The instant invention relates to a process for the preparation of titanium metal from an ore comprising titanium oxides which process comprises the steps of fluorinating the ore to convert the titanium oxides to titanium fluorides and then reducing the titanium fluorides to the metal. Such reduction may be carried out by contacting the titanium fluorides as a molten salt mixture with a molten alloy of zinc and aluminum at conditions whereby titanium is converted into a titanium-zinc alloy and the aluminum is converted into fluorides of aluminum. The titanium zinc alloy is separated from the fluorides of aluminum and the zinc is distilled from the alloy to leave behind titanium sponge. The ore may be an ilmenite ore and the fluorination may be carried out by contacting said ilmenite ore with a fluosilicate salt such as sodium fluosilicate.
