Abstract

Предлагается способ получения соли, такой как вольфрамат натрия, с использованием пирометаллургического процесса. Осуществляется процесс ошлаковывания, в котором металлсодержащий материал расплавляется в присутствии шлакообразующих веществ, таких как метасиликат натрия и кремнезем. Металл в основном концентрируется в более плотной металлсодержащей фазе. Более плотная металлсодержащая фаза затем может быть подвергнута барботированию углеродсодержащим газом для получения карбида металла, предпочтительно карбида вольфрама.Международная заявка была опубликована вместе с отчетом о международном поиске.
