What is Spodumene? 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 was the most important ore …

Spodumene is a lithium aluminum silicate with a hardness of 6.5 to 7 on the Mohs scale. It typically exhibits excellent transparency and a vitreous luster when cut and polished. Spodumene can often be distinguished by its crystal habit, fracture, and perfect prismatic cleavage, a property it shares with diamond and topaz.

Spodumene is a fairly prevalent mineral, but mostly dull and uninteresting in its most common forms. However, its two distinctly colored transparent varieties, Kunzite (pink) and Hiddenite (green) are very aesthetic and valued as gemstones. Hiddenite is much rarer than Kunzite, and can is highly valued, especially the deeper green color forms.

Spodumene is a member of the pyroxene family and one of the rare minerals of the element lithium with lithium aluminium silicate chemical formula. Spodumene takes its name from a Greek word meaning burnt to ashes, with reference to the grey color of the non-gem mineral. Spodumene crystallises in the monoclinic crystal system.

Hiddenite is the yellow-green to green variety of the silicate, Spodumene, and is named for William Earl Hidden who discovered it in 1879 in Alexander County, North Carolina, USA. The town there was later renamed Hiddenite, for the mineral, and its mines are still active today.

Lithium is most commonly extracted from spodumene. Naturally occurring β- spodumene is converted α-spodumene by heating to 1100˚C. α-spodumene which is less dense is crushed and then mixed with sulphuric acid and heated to 250˚C, and extracting it into water producing a lithium sulphate (Li 2 SO 4) solution. It is then treated with soda ...
