Abstract
Ferric chloride from the selective chlorination of titaniferous material such as ilmenite is partially oxidized to obtain a chlorine-rich stream and byproduct iron oxide. Unreacted ferric chloride is separated as solid particles from said stream and at least a portion of said particles are returned to the chlorination operation for absorbing heat generated in such operation.
