Claims (3)

1. Способ комплексной переработки отработанных растворов гальванического производства, заключающийся в нейтрализации с последующим выделением твердой фазы в виде гидроксидов металлов, отличающийся тем, что гидроксиды металлов переводят в оксиды путем нагрева до температуры не менее 900oС с последующим восстановлением при температуре, превышающей температуру плавления металлов.1. The method of complex processing of spent solutions of galvanic production, which consists in neutralizing with the subsequent separation of the solid phase in the form of metal hydroxides, characterized in that the metal hydroxides are converted into oxides by heating to a temperature of at least 900 o With subsequent recovery at a temperature exceeding the melting temperature metals. 2. Способ по п.1, отличающийся тем, что восстановлением оксидов проводят при 1200-2000oС.2. The method according to claim 1, characterized in that the reduction of the oxides is carried out at 1200-2000 o C. 3. Способ по п. 1 или 2, отличающийся тем, что восстановление оксидов проводят в среде углерода. 3. The method according to p. 1 or 2, characterized in that the reduction of the oxides is carried out in a carbon medium.
