Abstract
The results for one variant of processing high-silicon aluminum raw materials—Indian condalites—are given. It is established that the main impurity (silicon dioxide) can be removed in a sequential variant of Bayer hydrochemistry with the processing of red slime in high-module solutions by hydrogarnet technology. The formation conditions of ferrous hydrogarnet of the composition 3CaO · Fe2O3 · 2SiO2 as a monomineral (prevailing) phase, such as a temperature of 230–250°C, an alkali concentration no lower than 200 g/dm3, and the introduction of the active form of iron oxide, are determined.
