Özet
Most of boron minerals, such as colemanite, tincal and ulexite, include water of crystallization. Applying the calcination process, they lose some of their water of hydration at various calcination temperatures. Dehydration process can be applied due to technological and economical reasons. A porous solid may obtain by calcination process, and the rate of boric acid extraction from mineral can be increased. The effects of some parameters to prepare calcined ulexite for purpose of use in the leaching process were investigated in this study. The dehydration of ulexite was performed by using isothermal and nonisothermal methods. The effects of temperature, heating time, particle size and sample weight on the weight loss of ulexite were investigated. It was determined that an increase in dehydration temperature and heating time, and decrease in sample weight caused a significant increase in the weight loss of ulexite. The change in particle size does not have any significant effect on the dehydration rate.
