A systematic investigation on the extraction of boron from salt lake brine using 2-ethylhexanol as the extractant is reported with an emphasis on the extraction thermodynamics and extraction process design in order to obtain high purity boron product. The extraction parameters were optimized with respect to the time of extraction, volume percentage of extractant, phase ratio, and the concentration...
The decomposition of NaCaHSiO 4 is an important step in the hydro-chemical process to recover sodium when treating red mud. In this study, the phase transformation during the NaCaHSiO 4 decomposition and the key influential factors, including sodium concentration, reaction temperature, CaO addition and particle size were investigated. In addition, the sodium content in the residue,...
