Abstract

Данное изобретение относится к способу удаления железа в виде гематита из раствора сульфата цинка, проводимому при атмосферных условиях в ходе получения цинка электролизом. Согласно этому способу устанавливают значение pH содержащего железо раствора по меньшей мере 2,7, в раствор подают содержащий кислород газ и часть полученного таким образом гематита подают рециклом на операцию осаждения.Международная заявка была опубликована вместе с отчетом о международном поиске.
