Microwave-enhanced sulfate roasting for lithium extraction …
The extraction of lithium from lepidolite using sulfate follows the ion exchange mechanism, as illustrated in Fig. S4 (Ncube et al., 2021). The ionic radius of Li + (0.68 Å) is comparable to that of Fe 2+ (0.74 Å), which makes Li + and Fe 2+ prone to undergo isomorphous substitution during the mineralization process.
