Abstract

Предложен способ извлечения ценных цветных металлов из оксидной руды, где руда включает металл первой группы, выбранный из никеля, кобальта и меди. Данный способ включает уменьшение размера частиц руды, чтобы соответствовать последующей технологической операции, обеспечение контакта для элементов-металлов, контакт руды с хлоридом железа(III) или хлоридом железа(II), гидратированным или безводным, с образованием смеси руды и хлорида железа(II) или хлорида железа(III), приложение к смеси руды и хлорида железа(III) или хлорида железа(II) достаточной энергии для разложения хлоридов на хлористо-водородную кислоту и оксиды железа из второй группы, образование их соответствующих хлоридов, селективное растворение полученных хлоридов цветных металлов, оставление металлов в виде оксидов и в твердом состоянии и извлечение растворенных ценных цветных металлов из водного раствора.
