Abstract
In a process for recovering titanium metal values from a titanium bearing source which also contains iron, the source is subjected to a reductive roast followed by a leach of the reduced source with hydrogen chloride. The suppression of the dissolution of titanium during the leaching step of the process will be effected by the addition of a phosphoric acid to the leaching solution.
