ABSTRACT:
Titanium metal values may be recovered from a titanium bearing source such as an ilmenite ore by subjecting the source to a reductive roast, leaching the reduced source with a halogen-containing compound followed by crystallization of the iron halide impurity which is separated from the soluble titanium halide. The soluble titanium halide is then treated with an iron oxide to form titanium dioxide. The yield of titanium dioxide may be greatly improved by effecting the nucleation of the titanium in a manner which comprises adding the iron oxide to the solution without agitation. Upon completion of the nucleation reaction, the solids are then thoroughly dispersed before removing the solid titanium dioxide.
