Investigation of Dissolution Kinetics of Tincal Mineral in Ammonium Acetate Solution in High Solid / Liquid Ratios

Abstract

The chemical formula of tincal mineral used in this study is Na20-2B203-10H20. The tincal ore, one of the important boron minerals, is extracted around Eskişehir in Turkey. Herein, we investigated the kinetics of dissolution in different parameters such as concentration, particle size, solid / liquid ratio, mixing speed and reaction temperature in the ammonium acetate solution of tincal mineral. As a result, boric acid production obtained by dissolution of tincal mineral in amunium acetate solution increased with temperature increase. However, in the dissolution process, boric acid production was found to be reduced by the increase in particle size and solid-liquid ratio.
