Abstract: A process for the recovery of magnesium from a solution containing soluble magnesium, the process comprising, precipitating magnesium hydroxide from the solution, forming an oxide blend including magnesium oxide derived from the precipitated magnesium hydroxide together with calcium oxide, reducing the oxide blend to form a magnesium metal vapour and condensing the vapour to recover magnesium metal.
Abstract: A metallic article made of metallic constituent elements is fabricated from a mixture of nonmetallic precursor compounds of the metallic constituent elements. The mixture of nonmetallic precursor compounds is chemically reduced to produce an initial metallic material, without melting the initial metallic material. The initial metallic material is consolidated to produce a consolidated metallic article, without melting the initial metallic material and without melting the consolidated metallic article.

Abstract: A method is disclosed wherein elemental magnesium is produced from a supply of magnesium hydroxide or other magnesium based material. The magnesium hydroxide is combined with a HI gas to produce a magnesium iodide. The resultant magnesium iodide is then heated to separate the magnesium from the iodine.
Abstract: The present invention provides a method for producing a metal vapor that includes the steps of combining a metal and graphite in a vessel to form a mixture; heating the mixture to a first temperature in an argon gas atmosphere to form a metal carbide; maintaining the first temperature for a period of time; heating the metal carbide to a second temperature to form a metal vapor; withdrawing the metal vapor and the argon gas from the vessel; and separating the metal vapor from the argon gas. Metal vapors made using this method can be used to produce uniform powders of the metal oxide that have narrow size distribution and high purity.
Abstract: A continuous process for the production of elemental magnesium is described. Magnesium is made from magnesium oxide and a light hydrocarbon gas. In the process, a feed stream of the magnesium oxide and gas is continuously fed into a reaction zone. There the magnesium oxide and gas are reacted at a temperature of about 1400.degree. C. or greater in the reaction zone to provide a continuous product stream of reaction products, which include elemental magnesium. The product stream is continuously quenched after leaving the reaction zone, and the elemental magnesium is separated from other reaction products.
