Spodumene is a pyroxene mineral consisting of lithium aluminum inosilicate. It has a vitreous luster and occurs in a range of colors. The purplish or lilac variety is called kunzite, and the yellowish-green or emerald-green variety is known as hiddenite. Other crystals range from colorless to yellow. The crystals are often quite large.
Spodumene effectively separated from feldspar and quartz at a Mg(II) concentration of 1.03 mmol/L, at which the recoveries of spodumene, feldspar, and quartz were 85.5%, 10.2%, and 5.4%, respectively. As shown in Fig. 5 (c), the ability of Fe(III) to improve the flotation of spodumene was stronger than those of the other metal ions.

The spodumene associated with the locked (4–5%) and middling (15–26%) classes in both Pil2 and Pil3 samples are much less than the Pil1 sample. The spodumene particles in the locked class in Pil2 consists of low abundance of spodumene at 3 wt%, associated mainly with quartz (59 wt%) and moderated amounts of feldspars (29 wt%).
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.
The pure mineral samples of spodumene and feldspar (albite) were obtained from the Jiajika Lithium Mine, Ganzi District of Sichuan province, China. The samples were hand-picked, crushed and ground in a laboratory porcelain mill, and −0.074 mm fractions were used in the experiments.Chemical composition analysis (Table 1) and X-ray …

Spodumene was first described in 1800 for an occurrence in the type locality in Utö, Södermanland, Sweden.It was discovered by Brazilian naturalist Jose Bonifacio de Andrada e Silva.The name is derived from the Greek spodumenos (σποδούμενος), meaning "burnt to ashes", owing to the opaque ash-grey appearance of material refined for use in industry.
The spodumene pegmatites are unzoned and consist of medium-to very coarse-grained spodumene, plagioclase, K-feldspar, quartz, muscovite, and accessory amounts of beryl, manganoan fluorapatite,...
Due to the refractory nature of α-spodumene (LiAlSi2O6) and petalite (LiAlSi4O10), two major lithium minerals, conventional lithium recovery processes involve a high-temperature pre-treatment (>1000 °C) to induce a phase transition to tetragonal β-spodumene, an open structure allowing easier access to lithium through ion exchange. …
