Abstract

Способ разделения циркония и гафния в смеси ZrClи HfClс содержанием Hf 3 мас.% и менее от Zr+Hf, включающий в себя следующие этапы: 1) гидролиз смеси ZrClи HfClв водном растворе сильной неорганической кислоты с целью получения кислого водного раствора, содержащего 7-12 молей кислоты на 1 л; 2) пропускание полученного на этапе 1) раствора через ионообменную смолу; 3) при необходимости, элюирование части кислого водного раствора, обогащённого гафнием; 4) промывка смолы от кислого раствора, содержащего Zr и Hf; 5) пропускание через смолу водного раствора для отделения соединений циркония, связанных со смолой, и извлечение обогащённой цирконием фракции.
