ABSTRACT:
Ilmenite, one of the two natural occurring ores containing Titanium metal, is plentiful in comparison to the other, Rutile. However, Ilmenite can hardly compete with Rutile for Titanium metal production due to it's iron content, while Rutile includes only the oxides of Titanium (TiO.sub.2). Consequently, vast deposits of Ilmenite are not presently utilized for Titanium metal production because of the initial costs incident to first removal of the iron oxides from such ore so as to bring it to the proper chemical configuration (Rutile-like TiO.sub.2) for subsequent reductions to the metal; and thus that ore's vast deposits are not so utilized. Instant process utilizes powdered Ilmenite ore without such first removal of the iron oxides, and operates to produce a high grade Iron-Titanium alloy metal. The powdered ore is mixed with a solution containing primarily phosphoric acid, zinc oxide, and a sulfated surfactant. A carbonate of either of the Classes I-A or II-A Metals is added to the solution and the mixture is brought to a boil, allowing the volatile materials to vaporize to form dry, solid residue. The residue is then smelted to yield the alloy metal.
