Resumo
This work presents the results of experimental studies of leaching aluminosilicate and quartz impurities from leucoxene from the Yaregskoe deposit by sodium hydroxide solution by sodium hydroxide solution. According to the data, the type of kinetic equation of SiO2 dissolution is defined, as are the equation parameters, including the orders by the reagents, the preexponential factor, and the activation energy. The activation energy of 77.2 ± 3.9 kJ/mol corresponds to the kinetic region of the reaction behavior.
