Abstract

Способ извлечения оксида магния из источника сульфата магния, включающий этапы (а) получения источника сульфата магния в растворе, который получен как часть процесса, связанного с выщелачиванием металлосодержащей руды или концентрата; (b) превращения растворенного сульфата магния в твердый сульфат магния; (с) контакта твердого сульфата магния с элементарной серой в восстановительной атмосфере и (d) извлечения магния в виде оксида магния и серы в виде газообразного диоксида серы.
