Investigation dissolution behaviours and kinetics parameters of ulexite in boric acid solution

Nowadays, boron and its derivatives are widely used in industrial and technological areas. Boron minerals are the main sources for obtaining pure boron chemicals in the usage of different applications such as the defense industry, health, industry, kitchen equipments, etc. In this paper, for the first time, it has been reported the dissolution behaviors and kinetics parameters of ulexite in the boric acid solution. To solve ulexite by boric acid is important, because boric acid as a solvent prevents the formation of impurities, and therfeore our study is a first in the literature. In this context, the dissolution of the ulexite has been investigated under various experimental parameters such as temperatures, acid concentration, solid/liquid ratio, particle size, dissolution rate, and stirring speed. The experimental findings shown that the dissolution kinetics of ulexite increase with an increase in temperature and acid concentration and a decrease in particle size, but decrease with mixing speed in the acid. Moreover, the dissolution of ulexite in boric acid and activation energy were evaluated. As a result, it was found that the dissolution kinetics were compatible with the chemical control model and the activation energy was 22.024 kJ mol-1.
