Abstract
The technological substantiation of the process flowsheet for low-quality bauxite, nepheline, coal fly ash and other kinds of raw materials with high silica content processing by hydrochemical method is presented. According to this process, silica changes to calcium hydrosilicate in autoclave conditions at the low concentration of the caustic. This allows conducting the alumina production at low consumption of energy resources, high regeneration of the heat and at the low vapor consumption for the liquor evaporation. Besides the hydrochemical method may be used to different kinds of alumina content processing solid waste. Thus the ecological problems are solved. Besides the hydrochemical method processing may be used to various kinds of alumina content processing solid waste. Thus environmental problems may be solved.
