Claims
- 1. A process for removing chemisorbed and interstitial chlorine and chlorides from a titanium dioxide beneficiate - carbon mixture having a temperature of 900.degree. to 1080.degree. C. produced by reacting under fluidizing conditions, chlorine with a titaniferous ore, having a particle size of 100 to 200 mesh, mixed with 5 to 35%, by weight, of particulate carbon, at a temperature of 900.degree. to 1080.degree. C. comprising contacting, under fluidizing conditions, said beneficiate - carbon mixture with steam, moist air or moist inert gas at a flow rate of at least 0.5 ft/sec., exiting chemisorbed and interstitial chlorine and chlorides liberated thereby and cooling said beneficite - carbon mixture to a temperature of 150.degree. to 350.degree. C.
- 2. The process of claim 1 wherein the temperature of the beneficiate - carbon mixture is initially 1000.degree. to 1080.degree. C.
- 3. The process of claim 2 comprising contacting the beneficiate - carbon mixture with water at a rate where film boiling of the water maintains fluidizing conditions.
