Claims (2)

1. Способ извлечения благородных металлов из полупродуктов, включающий окислительный обжиг полупродуктов, восстановительную плавку огарка с глетом и коллектирование благородных металлов в свинец, отличающийся тем, что глет и огарок перед плавкой растворяют в расплаве галогенидов щелочных и/или щелочноземельных металлов, затем глет восстанавливают твердым углеродистым материалом из раствора в расплаве-растворителе при температуре свыше температуры плавления галогенида, благородные металлы коллектируют в образующийся свинец, который концентрируют в донную фазу, отделяемую от раствора оксидов в расплаве-растворителе.1. A method of extracting precious metals from intermediates, including oxidative roasting of intermediates, reducing smelting of cinder with litharge and collecting precious metals into lead, characterized in that the litharge and cinder are dissolved in a melt of alkali and / or alkaline earth metal halides, then the litharge is reduced by solid carbon material from a solution in a melt-solvent at a temperature above the melting point of the halide, noble metals are collected in the resulting lead, which concentrated in the bottom phase was separated from the solution of oxides in the melt-solvent. 2. Способ по п. 1, отличающийся тем, что в качестве расплава галогенидов используют расплав криолита. 2. The method according to p. 1, characterized in that the cryolite melt is used as a halide melt.
