Abstract

Изобретение относится к способу и установке для извлечения никеля и кобальта экстракцией оксимом из не содержащего алюминия и железа раствора выщелачивания, получаемого при кислотном выщелачивании никелевого латерита. Способ осуществляют при рН от 4 до 5,5 и при температуре менее 100°С. В качестве предварительных этапов способ также может включать кислотное выщелачивание никелевого латерита и удаление алюминия и железа. Кроме того, способ может включать извлечение никеля и кобальта из раствора, содержащего никель и кобальт, полученного при экстракции оксимом.
