Furthermore, lithium is essential for the production of energy storage devices (Choubey et al., 2016, Jaskula, 2018). α-Spodumene, α-LiAlSi 2 O 6, is the most abundant lithium mineral in nature with theoretical Li 2 O content of 8.03% w/w (Choubey et al., 2016). The α phase has a compact crystalline structure and low reactivity.

Lithium is an element valuable for the production of glass, aluminum products, and batteries. It is mined from ores of petalite (LiAl(Si2O 5) 2, lepidolite K(Li,Al) 3 (Al,Si,Rb) 4 O 10 (F,OH) 2, spodumene LiAl(SiO 3) 2 and also subsurface brines. Australia and Chile are the world's largest producers of lithium.

Therefore, extracting lithium from α-spodumene is challenging because the extraction conditions are harsh. It is of great significance to develop a new technology for the direct extraction of lithium from α-spodumene. In this study, a sustainable and efficient lithium extraction technology from α-spodumene is proposed. This process does not ...

Processing spodumene for lithium is challenging as it requires a high temperature transformation of the natural α-monoclinic form to β-tetragonal form, usually followed by acid baking and digestion. ... However, their approach requires high concentration of NaOH and special equipment (autoclave) in addition to long processing time. Owing to ...
