Spodumene; Spodumene is a pyroxene member of inosilicate mineral with chemical formula is LiAl(SiO3)2, lithium aluminium. It can also be pink, lilac, or green. Crystals are prismatic, flattened, and typically striated along their length. Gem varieties of the mineral usually exhibit strong pleochroism. Spodumene is an important ore of lithium.
Calcination of spodumene is a pre-treatment stage in preparation for sulfation roasting and leaching in lithium recovery. During calcination, α-spodumene (less reactive, monoclinic crystal...
Kunzite is the pink variety of spodumene. It is primarily from Afghanistan. Strongly pleochrotic, the crystals are colorless on the long axis and pink to violet down the C axis. The stronger the color, the higher the value, but …
It was found that activation of spodumene by calcium ions makes the surface charge less negative due to the adsorption of Ca2+ on the surface. The crystallographic properties of spodumene were...
β-spodumene. The α-spodumene is virtually refractory to hot acids. As a result of the phase transformation, the spodumene crystal structure expands by about 30% and becomes amenable to hot sulphuric acid attack. Due to this expansion, the specific gravity of the spodumene decreases from 3.1 g/cm3 (natural α-spodumene) to around 2.4 g/
Spodumene is from the Greek word spodumenos which means "burnt to ashes." This is a reference to its most common color. You will rarely find gray spodumene cut as gems, but the other colors can be spectacular. …
generally barren of spodumene and is composed of quartz, albite, microline, mica, and accessory cas- siterite. The spodumene-rich core of this deposit contains about 20 pct spodumene; range in grade is from 15 to 35 pct. Spodumene crystals are uniformly oriented in a nearly horizontal position normal to the walls.
We describe their mutual relationships: where spodumene is an early magmatic phase, petalite precipitates directly from a late orthomagmatic fluid, the spodumene remaining metastably, whereas eucryptite is …

A new spodumene-rich pegmatite was recently discovered on the north side of Plumbago Mountain, Oxford County, Western Maine. The site is about 1.5 km northwest of the famous Dunton gem tourmaline pegmatite. It is an albite-quartz-spodumene pegmatite containing gigantic crystals of spodumene and montebrasite.
Gibson et al. (2021) performed a heavy liquid and dense media separation test of Hidden Lake, Canada's pegmatite ore to demonstrate a pre-concentration stage to recover coarse-grained liberated...
The paper investigates trace elements and crystal-rich fluid inclusions in spodumene from rare-metal pegmatites of the Kolmozero lithium deposit in the Kola region, Russia. The main lithium mineral in the pegmatites is spodumene, which occurs in three generations, designated as Spd-I, Spd-II and Spd-III. Iron, Na and Mn are the most typical ...

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.
The major minerals are quartz, potassium feldspar, albite, and muscovite; typical accessory minerals include biotite, garnet, tourmaline, and apatite. The principal lithium ore minerals are spodumene, petalite, and lepidolite; cesium mostly comes from pollucite; and tantalum mostly comes from columbite-tantalite.

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.
