Abstract
837,067. Concentrating amalgams; extracting refractory metals. ETHYL CORPORATION. May 1, 1958, No. 13911/58. Class 82(1) An alkali metal enriched amalgam, which may be used as a reducing agent for refractory metal halides, is continuously obtained from a dilute amalgam by feeding the dilute amalgam to a boiling alkali metal enriched amalgam which is partly heated by compressing the evolved mercury vapour and condensing it in a heat exchange coil immersed in the amalgam. Additional heat is supplied when required by an electric immersion heater, and the dilute amalgam is preheated by the hot, alkali metal enriched amalgam removed from the vaporization chamber. In a modified method mercury is vaporized from a thin film of amalgam which is arranged to flow over a weir and pass down the inside of a vertical tube the outside of which is heated by hot compressed mercury vapour. To produce a refractory metal, an amalgam, preferably containing from 3 to 10% by weight of sodium is reacted with a refractory metal halide at a temperature between the boiling point of the amalgam and 1500‹C. A particular embodiment, as shown, describes the production titanium by feeding the amalgam, at its boiling point through the inlet 52 into the reactor 50 heated to about 500‹C. where it reacts with titanium tetrachloride supplied through inlet 51. A mixture of mercury vapour, sodium chloride particles and titanium particles is withdrawn by the suction hood 54 to the cyclone 53 from which mercury vapour passes via the outlet 56 and from which sodium chloride and titanium particles pass via the pipe 55. The titanium and sodium chloride may be separated by vacuum distillation.
