Cinética de la disolución de ulexita calcinada en soluciones de sulfato de amonio

摘要: Ulexite is one of the boron minerals, which include a respectable amount hydration water. It can be used as raw material in production compounds. Some part water composition ulexite removed from solid matrix applying dehydration treatment, and porous structure obtained to increase reaction rate. In present study, effect temperature on dissolution kinetics ammonium sulfate solutions was researched batch reactor utilizing parameters solution concentration, solid-to-liquid ratio, stirring speed temperature. determined that rate calcined increased with increasing concentration decreasing ratio. The highest attained sample at 150 °C. found fit first order pseudo-homogeneous model. activation energy process estimated 42 kJ·mol -1 .
