Extraction of lithium from primary and secondary sources

Lithium extraction from primary resources such as ores/minerals (spodumene, petalite and lepidolite) by acid, alkaline and chlorination processes and from brines by adsorption, precipitation and ion exchange processes, is critically examined. Problems associated with the exploitation of other resources such as bitterns and seawater are highlighted.

The Role of the Calciner in the Extraction of Lithium from

Spodumene ore naturally occurs in the crystal structure of monoclinic alpha form (α-form). In order to extract lithium from the ore via the leaching process, however, the ore’s crystal structure must be in the tetragonal beta form (β-form).¹ This conversion is achieved through decrepitation, or the shattering of
