Abstract

The
obtain of the boron compounds from Ulexite which is one of the most important
ores of Turkey is important. In this study, optimization of dissolution of
ulexite by pure CO₂ was investigated in aqueous media under pressure
in according to Taguchi method. Temperature, particle size, solid-to-liquid
ratio, reaction time and pressure were chosen as parameters for the studies carried
out in a high pressure-high temperature reactor. After dissolution experiments,
optimum conditions for the dissolution of ulexite were found as 75 g/300 g
water (A₁) for solid-to-liquid ratio, 15 bar (B₃) for CO₂
pressure, 80 ℃ (C1) for temperature, 60 min (D₃) for time and -150µm
(E₁) for particle size. The solutions obtained under optimum
conditions were dried using a spray drier. Further, after the solution was
concentrated, it was crystalized by cooling, and the crystals were filtered and
dried. Chemical
analyzes exhibited that the products obtained in both cases are sodium
pentaborate (Na₂B₁₀O₁₆₎with different water contents.
