Техногенные отходы как сырье для получения наноразмерного диоксида кремния

Abstract

The processes of the solid-state and hydrochemical fluorination process of alumina production from red mud and waste after wet magnetic separation of titanium magnetite ores by ammonium hydrogen fluoride was studied. Data on changes in the phase composition of the raw materials, the conditions of formation and decomposition of intermediate compounds were obtained.
