The Role of Calcination 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 the crystal structure.

Direct Extraction of Lithium from α-Spodumene by Salt
In recent years, several methods have been reported to extract lithium (Li) from spodumene. However, the majority of them still require the transformation of the naturally occurring spodumene phase (α) to the more reactive crystalline phase (β) by calcination at 1100 °C. To address the economic drawbacks and high greenhouse gas emission of ...

Spodumene: The Lithium Market, Resources and Processes
2019-5-29 Spodumene is an aluminosilicate of lithium. It has been described for the first time in 1800 for an occurrence in Üto, Sweden [ 31 ]. Its name is derived from ancient Greek spodumenos, which means “burnt to ashes”, due to its grey ash-like color when grinded. Its color ranges from green to purple.
