ABSTRACT:
Ores containing oxides of Titanium, Zirconium and Hafnium metals are reduced by mixing them in the powdered state with a base hydroxide of one of the Classes I-A or II-A metals of the periodic table of elements and either sugar or starch, mixing them well, then heating the mixture until ignition begins and maintaining the necessary heat until ignition is finished. The remaining residue is then flushed and boiled with water to remove waste chemicals, leached with hydrocarbon solvents, hydrochloric acid, again boiled with water, flushed, dryed, and then smelted to Class IV-B metal powder or ingot.
