Dissolution kinetics of ulexite in acetic acid solutions

摘要: Abstract Ulexite is an important boron mineral used for the production of compounds. The aims this study are to examine dissolution kinetics ulexite in acetic acid solutions, and present alternative process produce boric acid. In order investigate concentration solution, reaction temperature, solid-to-liquid ratio, particle size were selected as experimental parameters. It was determined that rate increased with increasing solution temperature decreasing ratio. activation energy found be 55.8 kJ/mol.
