| 20130220077 | Method and apparatus for high temperature production of metals - Carbothermic reduction of magnesium oxide at approximately 2200 degrees Kelvin yields a high temperature mixture of magnesium vapors and carbon monoxide gas. Previous processes have sought to cool or alter the mixture to cause the yield of pure magnesium, which is then used in subsequent processes for its reducing properties. The present invention takes advantage of the stability and inertness of carbon monoxide at elevated temperatures enabling the magnesium vapor/carbon monoxide gas mixture from the carbothermic process to be used directly for the production of other metals at high temperatures. Chromium oxide, manganese oxide, zinc oxide and sulfide, and several other metal compounds can be reduced by the magnesium vapor/carbon monoxide gas mixture at temperatures high enough to prevent the gas mixture from back-reacting to magnesium oxide and carbon. | 08-29-2013 |
| 20150368752 | PRODUCTION PROCESS - A process for the production of a metal which comprises: carbothermal reduction of the corresponding metal oxide to produce a mixed gas stream comprising the metal and carbon monoxide; maintaining the mixed gas stream at a suitably elevated temperature to prevent reformation of the metal oxide; ejecting the mixed gas stream through a convergent-divergent nozzle in order to cool the mixed gas stream instantaneously to a temperature at which reformation of the metal oxide cannot take place; and separating and collecting the metal, wherein the nozzle is heated by means other than gas flow through the nozzle so that temperature of surfaces of the nozzle in contact with the mixed gas stream are maintained at a temperature sufficient to prevent deposition on the said surfaces of products from the gas stream. | 12-24-2015 |
