Overall spodumene represents 26 % of the pegmatite at a grade of 2.4 % Li 2 O corresponding to 7.12 Mt of LCE. Lithium mining at Greenbushes commenced in 1983 although other commodities (tin and/or tantalum) has been mined from the same area in 1888 (Brown et al., 2016). Earl Grey, Mount Holland, Australia: 189 Mt of spodumene ore

Spodumene - A large cleaved crystal of Spodumene, an important or of lithium, found chiefly in fractionated pegmatites. The Harding mine was known for large masses of Spodumene. It was a primary ore of lithium along with a host of other lithium minerals from pegmatities. In recent years lithium has been extracted from low grade lithium salt basins …
Soon after mining began in 1919, the Harding Mine was shipping 800 tons of hand-cobbed lepidolite annually, along with smaller amounts of rose muscovite and spodumene. Then in 1924, two shipments were found to contain a mineral contaminant that was detrimental to glass …

The primary magmatic phases, spodumene (LiAlSi 2 O 6) and petalite (LiAlSi 4 O 10), are antithetic in terms of P and T, so that petalite is the high-T – low-P equivalent of spodumene in lithium-rich pegmatites (Krivovichev, 2004; London, 1984; Stewart, 1978). During the late stage of evolution of granitic pegmatites, residual fluids modify ...
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 gemstone s. Hiddenite is much rarer than Kunzite, and can is highly valued, especially the deeper green color forms.

hundred short tons of spodumene ore have been produced from pegmatites in New Mexico since 1920. Most of this production, which represents nearly 10% of the total U.S. production between 1920 and 1950, came from the Harding mine (Picuris district, County). A Taos small amount came from the Pidlite mine (Rociada district, San Miguel County).
Harding Mine, Picuris District, Taos County, New Mexico, USA Eucryptite has been known since the 1880s, but specimens are rarely available. The species gets its name from the Greek meaning "well concealed", as it was difficult to see in the first known specimens because it was often surrounded by or implanted inside albite.
