Spodumene is the major mineral found in the concentrate. It is well liberated but with few mineral associations. Spot "2" has a complex composition with Fe, Mg, Ca, Al, Si, O as the major elements but with varying concentrations at different spots. We attribute these grains to the amphibole group of minerals as indicated in XRD spectra due ...

spodumene may be milled using our ball mills and then transported to storage. The beta spodumene is then dosed from storage to a mixer where concentrated sulfuric acid is mixed with it. Following mixing, the spodumene/acid mixture is introduced to our acid roaster, an indirect fired kiln, where a chemical reaction occurs

Spodumene flotation stands as the most commonly used method to concentrate lithium minerals. However, it faces significant challenges related to low collector recoveries and similarity in the surface characteristics of the minerals, which make the effective separation of this valuable mineral difficult. For this reason, numerous …

The coarse fraction was ground to less …

The Freemans argue that spodumene is a rock, not a metal, and should fall under the state's quarrying regulations. The end product also matters: In an appeal filed in Superior Court, the couple says they plan only on excavating and selling the larger spodumene crystals, not processing them for the metal (lithium) they contain.

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. Some …

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/
