A method to extract and refine metal products from metal-bearing ores, including a method to extract and refine titanium products. Titanium products can be extracted from titanium-bearing ores with TiO.sub.2 and impurity levels unsuitable for conventional methods.

A method for preparing titanium or titanium aluminum alloys through two-stage aluminothermic reduction and obtaining titanium-free cryolite as byproducts. The method has the following steps: (1) using sodium fluoride and sodium fluotitanate as raw materials, or using sodium fluotitanate as raw materials, and using titanium aluminum alloy powder as a reducing agent; (2) mixing and pressing into pellets, and carrying out first-stage aluminothermic reduction and vacuum distillation; (3) finely grinding after taking out titanium-containing cryolite, mixing with the reducing agent and briquetting, and carrying out second-stage aluminothermic reduction; and (4) separating low-titanium titanium aluminum alloys from high-titanium titanium aluminum alloys, making the low-titanium titanium aluminum alloys and the high-titanium titanium aluminum alloys into powder and returning to the two-stage aluminothermic reduction as the reducing agent; or after the alloys are molten, making the alloys into powder for the two-stage aluminothermic reduction.

A method is provided for the production of titanium-aluminum-vanadium alloy products directly from a variety of titanium and vanadium bearing ores that reduces the processing steps significantly as compared to current TiAlV alloy production methods.

A method for producing a metal powder that combines molten reducing metal and metal halide in a space that is substantially free of oxygen and water, wherein the molten reducing metal is sodium and/or potassium, or aluminum (or magnesium or titanium) and is present in a stoichiometric excess to the metal halide which is a solid or liquid, thereby producing metal particles and salt, removing unreacted reducing metal, optionally removing the salt, and recovering the metal powder, is described. A method for producing a metal masterbatch wherein the molten reducing metal is aluminum, magnesium, and/or titanium and after combining molten aluminum (or magnesium or titanium) and metal halide in the reaction space, substantially removing the produced metal salt to obtain the metal masterbatch which comprises at least a portion of the molten aluminum (or magnesium or titanium) and at least one metal also is described.

Disclosed herein is a novel approach to the chemical synthesis of titanium metal from a titanium oxide source material. In the approach described herein, a titanium oxide source is reacted with Mg vapour to extract a pure Ti metal. The method disclosed herein is more scalable, cheaper, faster, and safer than prior art methods.
