Extraction of lithium from lepidolite by sulfation ...

Jul 18, 2012  The most important processes for the extraction of lithium from lepidolite are the sulfate acid and the lime methods (Distin and Phillips, 1982). However, the extraction of lithium by sulfate acid method uses high concentration acid and the purification procedure is complex. The lime process uses limestone and requires a large amount of energy.
