Spodumene is the principally mined lithium-bearing mineral due to its high theoretical lithium content of about 8.1% Li 2 O [18]. Significant contributions have been made towards providing a critical review of the processing and recovery of lithium from different resources, such as brines, pegmatites, and seawater.

Spodumene is a pyroxene mineral that is typically found in lithium-rich pegmatites. It is usually associated with other lithium minerals such as lepidolite, eucryptite, and petalite. Spodumene has a chemical composition of LiAlSi 2 O 6 but small amounts of sodium sometimes substitute for lithium. Throughout most of the 20th century, spodumene ...

Spodumene is known to preferentially release its Li content during weathering (Singh and Gilkes, 1993) because the Li atom is a weakness in the crystal structure due to its small size (London, 2017). With feldspars making up to 50 wt% of the samples, elements Ca, Na, and K, are also notable solutes in the leachates. In columns, Ca distinguishes ...

Spodumene. Spodumene is a silicate mineral often referred to as lithium feldspar. Its mineral form is characterized by hard needle-like grains of brilliant white color. It is used in ceramics as a source of lithia. Lithia is a very powerful flux, especially when used in conjunction with potash and soda feldspars.

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 this …
