Turkey is the country having the largest boron reserves in the world. 72% of the world boron reserves is in Turkey. Commercial boron ores include colemanite, tincal and ulexite in Turkey. +3 mm ulexite fraction produced in ulexite concentration plant is exported, but -3 mm fraction, which has 16.6 % B2O3 cannot be sold and is piled up in the mine area. The Taguchi method has been used to determine optimum conditions for stabilization of CO2 gas with ulexite. Chosen experimental parameters and their ranges were (i) reaction temperature, 5-40 °C; (ii) solid-to-liquid ratio (in weight), 0.1-0.5; (iii) ; (iv) mean particle size; -600 -150 mm; (v) stirring speed, 300-700 rpm; (vi) reaction time, 15-120 min. The optimum conditions were found to be reaction temperature, 40 °C; solid-to-liquid ratio, 0.1; mean particle size, -150 mm; stirring speed, 500 rpm and reaction time, 90 min. Under these optimum conditions and 29.78 L CO2/kg ulexite was stabilized.
