Applicability of Hydrogamet Technology for Complex Processing of Indian Condalites

摘要

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 hydrogamet technology. The formation conditions of ferrous hydrogamet of the composition 3CaO ? Fe_2O_3 ? 2SiO_2 as a monomineral (prevailing) phase, such as a temperature of 230-250°C, an alkali concentration no lower than 200 g/dm~3, and the introduction of the active form of iron oxide, are determined.
