Claims (1)

Способ восстановления металлов из смеси их оксидов, включающий растворение оксидов в расплаве галогенидов щелочных и/или щелочноземельных металлов, жидкофазное восстановление оксидов твердым углеродом при заданной температуре, отделение восстановленного металла от расплава-растворителя, который повторно используют для растворения исходного продукта, отличающийся тем, что восстановление менее прочного оксида ведут, постоянно поддерживая в расплаве-растворителе его концентрацию выше концентрации более прочного оксида путем непрерывной загрузки исходного продукта, причем при достижении концентрации более прочного оксида уровня концентрации менее прочного оксида растворение исходного продукта в расплаве-растворителе прекращают и восстанавливают смесь оксидов, отделяя полученный сплав от расплава-растворителя изолированно от металла, восстановленного из менее прочного оксида.The method of reducing metals from a mixture of their oxides, including the dissolution of oxides in a melt of halides of alkali and / or alkaline earth metals, liquid-phase reduction of oxides with solid carbon at a given temperature, the separation of the reduced metal from the melt-solvent, which is reused to dissolve the starting product, characterized in that the reduction of the less stable oxide is carried out by constantly maintaining its concentration in the melt-solvent above the concentration of the more durable oxide by continuous implicit load starting material, wherein when the concentration of more durable oxide concentration level less durable oxide dissolving the starting material in the melt-solvent is stopped and the reduced mixture of oxides, separating the resulting alloy from the dissolver melt separately from the metal recovered from the less durable oxide.
