Abstract
Titanium tetrachloride may be produced by chlorinating, at low temperatures with a minimum of added carbon, a highly reduced titaniferous slag consisting of the oxides and oxycarbide of titanium which is produced by smelting a mixture of 100 parts titaniferous iron ore and 17-25 parts carbonaceous reducing agent at a temperature of 1700-2300 DEG C. in an electric arc furnace, periodically adding more mixture, cooling and solidifying the furnace contents and separating the resultant solidified globules of metallic iron from the highly reduced titaniferous slag.ALSO:Iron is removed from titaniferous iron ore, to leave a highly reduced titaniferous slag consisting of the oxides and oxy-carbide of titanium, by smelting a mixture of 100 parts titaniferous iron ore and 17-25 parts carbonaceous reducing agent at a temperature of 1700 DEG -2300 DEG C. in an electric are furnace, periodically adding more mixture, cooling and solidifying the furnace contents and separating the resultant solidified globules of metallic iron from the highly reduced titaniferous slag. In the embodiment described, a mixture of ilmenite and coke in the appropriate proportions is charged into an alternating current are furnace (see Group XI) and the furnace is heated to 1800 DEG C. by an arc struck between an upper electrode and the charge. Successive charges of feed material are added to the furnace when the iron of the preceding charge has coalesced in globules. When the furnace is full the power is cut off and the furnace allowed to cool, a small amount of coke being added to prevent reoxidisation of the slag. The fused central core of highly reduced slag and iron globules is removed from the remaining partially reduced feed material in the furnace and is broken up and the iron globules separated, any remaining iron in the slag being removed by leaching and/or magnetic separation. The partially reduced feed material may be used as a constituent of the feed mixture or as a thermal insulation material for the furnace crucible and the iron globules, which are stated to have a composition similar to that of pig iron, may be collected and utilized.
