Abstract

Предложены способ и устройство для обработки титансодержащего шлака. Способ включает приведение титансодержащего шлака (2) в контакт с первым выщелачивающим раствором (4) серной кислоты для растворения примесей, содержащихся в шлаке, с получением первой суспензии. В данном способе первую суспензию (8) подвергают разделению (10) на твердую и жидкую фазы с получением первого выщелачивающего раствора серной кислоты, содержащего растворенные примеси из первого титансодержащего остатка (12) после выщелачивания.
