The chlorinati0n of ilmenite concentrates and slags to produce ticl4 suitable for pigment or metal production was investigated by the Bureau of Mines along with the dechlorination of byproduct iron chloride to produce chlorine for recycle and iron oxide. Ilmenite concentrates or slag powders were fed into the bottom of a fluidized coke bed at 1,050 deg c using chlorine flow rates up to 20 1/min in a 10.2-Cm-diam reactor. Tests showed that >95 pct of the various ilmenite concentrates reacted at optimum conditions, and recovery of ticl4 ranged from 95 to 100 pct of stoichiometric. Impurity dusts were removed from the vapors by cyclones and a fiberglass cloth filter. Iron chloride was condensed as a powder with less than 0.4 pct insoluble material. The ticl4 was collected in refrigerated condensers.
