Abstract

In this study, it was investigated the optimization of ulexite in both aqueous and borax pentahydrate solutions saturated with carbon dioxide. The effects of parameters such as solid-to-liquid ratio, reaction temperature, particle size and reaction time were investigated on dissolution of ulexite mineral. 2n factorial experimental design and orthogonal central composite design methods in the dissolution experiments were used. It was observed that the most effective parameters on the dissolution of ulexite were the solid-to-liquid ratio, the particle size and the reaction time in aqueous and borax pentahydrate solutions. The optimum conditions on maximum ulexite dissolution were as: the reaction temperature 85 °C, the solid-to-liquid ratio at 0.125 g mL-1, the particle size was 50 mesh and 90 min for reaction time. The chosen stationary parameters at the initial stage of the reaction were stirring speed 600 rpm and CO2 gas flow rate 514 mL min-1. Under these optimum conditions, the dissoluted B2O3 was 99.11 % in aqueous solutions and 99.02 % in borax pentahydrate solutions.
