Abstract
483,675. Distilling metals. BYRNE, E. L. W. (American Smelting & Refining Co.) Oct. 26, 1936, No. 29085. [Class 82 (i)] A process for separating a mixture of metals which exhibits a single phase at one temperature and at least two liquid phases at a lower temperature, comprises simultaneously subjecting different portions of a bath of such a mixture to distillation and liquation while effecting thermosiphonic circulation between the said portions. In treating a molten bath of zinc and lead, the zinc is distilled from one portion of the bath maintained at a temperature slightly in excess of 900‹ C. while the second portion of the bath is maintained at not more than 500‹ C. to separate the zinc and lead into layers, intercirculation and exchange of metal being effected between the two portions so as to maintain the lead content of that portion undergoing distillation at a low value. The process is carried out in a furnace divided by a wall 18 into a liquation chamber 19 and a distillation chamber 20, which are connected by ports 21, 22 in the wall. The metal in the chamber 20 is heated by tubes 23 of refractory material which are fired internally and some of the hot gases from the tubes may be diverted through the opening 25 into the chamber 19, the rest passing into an exit flue. Zinc vapours from the chamber 20 are removed through a flue 30. The solid material is fed by a shoot 27 into the furnace where it is first melted. The process may also be applied to the separation of zinc and selenium, zinc and bismuth, zinc and thallium, and also sodium and magnesium.
