Claims (1)

Способ переработки окисленных никель-кобальтовых руд путем восстановительного спекания и магнитного обогащения, отличающийся тем, что, с целью перевода оксидных соединений железа в магнетит, а никеля и кобальта в элементарное состояние, спекания ведут в среде острого пара при температуре 480-600oС с использованием в качестве восстановителя карбамида или другого органического вещества с повышенной температурой кипения и не содержащего серы, извлечение никеля и кобальта из концентрата проводят гидрометаллургическим путем или электростатической сепарацией.A method of processing oxidized nickel-cobalt ores by reductive sintering and magnetic enrichment, characterized in that, in order to convert oxide compounds of iron to magnetite, and nickel and cobalt in an elemental state, sintering is carried out in an atmosphere of hot steam at a temperature of 480-600 o C using urea or another organic substance with a high boiling point and not containing sulfur as a reducing agent, the extraction of nickel and cobalt from the concentrate is carried out by hydrometallurgical method or electrost nical separation.
