Abstract

Представлен усовершенствованный способ обогащения титансодержащего материала, который включает стадии восстановительного обжига титансодержащего материала, выщелачивание в минеральной кислоте, отличающийся тем, что титансодержащий материал перед восстановительным обжигом подвергают тепловой обработке в водном растворе минеральной кислоты для удаления радионуклидных примесей.An improved method for enriching a titanium-containing material is presented, which includes the stages of reductive roasting of a titanium-containing material, leaching in mineral acid, characterized in that the titanium-containing material is subjected to heat treatment in an aqueous solution of mineral acid to remove radionuclide impurities before reductive roasting.
