Regarding chemical demands, the results align with the existing literature. For the production of 1 kg of lithium carbonate from high-grade brine deposits in this study, 1,66 kg of sodium carbonate are required. Kelly et al. (2021) accounted for the usage of 2 kg of sodium carbonate, whereas Schenker et al. (2022) considered 1,9 kg.
A critical requirement arises for high-quality battery-grade lithium carbonate within the industrial settings. Currently, the main method for producing lithium carbonate is reaction crystallization.
For medium-grade brine deposits, the lithium concentration in this work is 0,035 wt%, slightly lower than the value considered by Chordia et al. (2022) (0,05 wt%). Consequently, slightly higher amount of sodium carbonate (2,14 kg) is used compared to Chordia's analysis (1,86 kg) for the production of 1 kg of lithium carbonate.
Kelly et al. (2021) accounted for the usage of 2 kg of sodium carbonate, whereas Schenker et al. (2022) considered 1,9 kg. The reagent values for the removal of magnesium (Mg) and calcium (Ca) also fall within a similar range, with any differences attributed to varying ratios and weight percentages of Mg and Ca between studies.
Moreover, increasing the reactant concentration significantly boost the recovery rates of lithium. The substitution of sodium carbonate solution with solid sodium carbonate represents the concentration threshold, offering maximal potential for augmenting lithium carbonate recovery rate.
Consequently, under optimized conditions, battery-grade lithium carbonate was synthesized, with an obtained lithium recovery rate of 93%, surpassing values reported in existing literature ( Zhang et al., 2019 ). Fig. 13. Characterization of battery-grade Li 2 CO 3 (a) XRD (b) SEM (c) PSD. 3.4.
