Conclusion

Processing of boron- and aluminosilicate ores, including danburite, argillite, zeolites, kaolin clays, and bentonite by acid and chloric methods is considered. Conducted researches on chloric and acid decomposition of boron- and aluminosilicate ores allowed to find the optimal conditions of raw materials decomposition with high output. Influence of temperature, process duration, and acid concentration on solubility of danburite from aluminium containing ores is studied. Kinetics of dissolution in acid in wide range of parameters change is studied as well. The activation energy is defined by means of Arrhenius equation. The kinetics of acid decomposition of argillite, zeolites, kaolin clays, and argillite is defined. The flowsheets of complex
