Production of Lithium –A Literature Review. Part 2. Extraction …
ABSTRACT. Spodumene is the main source of lithium among the lithium-containing minerals. A number of studies have been done on the extraction of lithium from naturally occurring α-spodumene as well as pre-treated β-spodumene and the effect of key factors that influence extraction and optimum processing conditions have been discussed.

A promising approach for directly extracting lithium from α …
As many researchers have studied, spodumene exists in nature in the form of α-phase with a monoclinic structure of the pyroxene type. This structure is resistant to the attack of chemical agents, either gaseous or liquid, which makes the direct extraction of lithium from α-spodumene almost unfeasible (Choubey et al., 2016).Therefore, in most extraction methods, α …
