    摘要: 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.

    摘要: Ores containing copper metal are reduced to the metal by mixing them with a carbonate catalyst, both being in the finely divided state, then mixing them with a chemical liquid solution comprised mainly of phosphoric acid, zinc oxide, and a sulfated surfactant which is in the concentrated state, or optionally water may be added, allowed to react chemically while stirring, then optionally boiled, then smelted at such temperatures as necessary to smelt (melt) the copper out of the mass (matrix).

    摘要: 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.
