  • Extraction of lithium from β-spodumene using sodium

    01/05/2018· The ion-exchange based mechanism is similar to that previously reported for methods using sulfuric acid (Xiao et al., 1997) and calcium chloride roasting (Barbosa et al., 2015) to extract lithium from β-spodumene, where Li + was replaced by H + and Ca 2+, respectively. However, this extraction process was built on strong base transforming to weak base in the alkaline atmosphere.
