Extraction of lithium from lepidolite by sulfation ...

2012-7-18  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.

Extraction of lithium from primary and secondary

2014-12-1  Lithium extraction from ores/minerals utilizes roasting followed by leaching, while its extraction from brines includes evaporation, precipitation, adsorption and ion exchange (Garrett, 2004). Lithium can be extracted from LIBs by leaching followed by precipitation, ion exchange or solvent extraction and electrolysis (Shuva and Kurny, 2013).

Comparison of Processes for Lithium Recovery from ...

2020-1-8  Before both chemical treatments, lepidolite was calcined at 800ºC and was transformed in a more reactive species, β-spodumene. The H2SO4 digestion at 175ºC (followed by water leaching) allowed 88% Li recovery into the solution in 30 min. By the contrary, the HCl leaching process carried out at 90ºC also achieved similar yields but only after 4 h of reaction. In both cases, an acid excess was used, but clearly higher for the essays with HCl. The H2SO4 digestion process was also advantageous in what concerns to selectivity over other contained metals. Al, Mn and Fe concentrations in solutions were substantially higher in the hydrochloric acid leaching.
