ABSTRACT: Value metal belonging to Group IA or IIA of the Periodic Table is recovered from its ore or concentrate by mixing the latter, in finely divided form, with an excess of molten lix- ivlant reaction metal. This forms a mixture of an alloy of the value metal and the reaction metal and a dispersate of partly depleted source material. Value metal is vacuum refined from the alloy and recovered. The method may be conveniently carried out, continuouly, in a closed vessel by the use of an apparatus according to the invention, having an upwardly extending treating passage for containing the reaction metal and extending upwardly to a vacuum space. Lifting gas is injected into the mixture to provide emission of the mixture in the form of a volley of drop- lets from which the value metal is vacuumed off. The remaining reaction metal and partly depleted source material are deposited in a catchment bath. The material from the catchment bath is partly recycled through a recycling passage to the reaction passage and partly passed to a reservoir for the reaction metal from which depleted source material is removed.Barometric legs lead from a submerged position in the reservoir to the bottom of the reaction passage and the bottom of the catchment bath respec- tively and electromagnetic pumps control the flow through these legs.
