“…However, if ions (AlO  2 and SO  2 4 ), which pass into solution during the reaction, are to be immediately removed from the system, then the reaction parameters will not change but will always remain in the intense zone. In this case, increasing the temperature does not make much sense, and the concentration of alkali can be reduced [19].…”

“…Studies have shown that alunitized rock decomposes with alkali solutions as easily as a pure mineral [4]. We studied the kinetic regularities of the leaching of alunite ore in alkaline solutions in [12]. Alunite ore is treated with the alkaline solution at a temperature of 95-98 0 C and leached within 30 minutes.…”

“…It is known that in alunite rocks, alunite is easily dissolved in solutions of caustic potassium (sodium) above 60 0 C, and at the same time, aluminum goes into the solution in the form of potassium (sodium) aluminate, as well as alkali metal sulfates. Quantitative characteristics of the alunite dissolution kinetics were studied in [18]. However, the extraction of gal-lium and vanadium from raw alunite ore into solution has not been studied.…”
