Scandium is rare, with only a very small amount of worldwide production per year. It is present in minute quantities in many minerals, notably monazite. However, it is only economical to extract it from uranium ore tailings and from the minerals euxenite, gadolinite and thortveitite.
Scandium is now produced mostly as a by-product of uranium extraction from the mineral davidite, which contains about 0.02 percent scandium oxide. Scandium exists in two allotropic (structural) forms. The α-phase is close-packed hexagonal with a = 3.3088 Å and c = 5.2680 Å at room temperature.
Mineral Processing and Extractive Metallurgy Review Overview On Extraction and Separation of Rare Earth Elements from Red Mud: Focus on Scandium

May 15, 2019 Nonetheless, separation of scandium from other REEs involved an additional solvent extraction step with di(2-ethylhexyl)phosphoric acid (D2EHPA). It appears that finding a scandium-selective sorbent could address the issue of its recovery and purification from dilute, yet complex solutions like BR leachates.
The principal scandium carrier minerals are ferrohastingsite (59 %) and ferrohedenbergite (40 %). Resource Modeling. The mag separation work suggested a scandium upgrade to approximately 346ppm, based on a resource material head grade of 160-200ppm, and a 72%
Due to the complex process for separation and purification of Sc from these ores, Sc is a kind of very expensive metals with high prices, which seriously obstructs its widely applications. As scandium and zirconium are commonly associated elements, Zr is a kind
Scandium is a chemical element with symbol Sc and atomic number 21. A silvery-white metallic d-block element, it was discovered in 1879 by spectral analysis of the minerals euxenite and gadolinite from Scandinavia. Scandium is a rare-earth metal, used in small amounts but with drastic effects on properties of matter.
Panguite is a type of titanium oxide mineral first discovered as an inclusion within the Allende meteorite, and first described in 2012.. The hitherto unknown meteorite mineral was named for the ancient Chinese god Pan Gu, the creator of the world through the separation of yin (earth) from yang (sky).
Jun 27, 2018 These included gravity separation, low-intensity magnetic separation and wet high-intensity magnetic separation. The non-optimized magnetic separation tests achieved 66% scandium recovery to 46% mass pull to mineral concentrate, shy of our targeted 50% rejection and 80-85% scandium recovery.

Jun 23, 2016 In the scandium extraction step, scandium values are extracted from a scandium source with an organic solvent, thereby obtaining a scandium-loaded organic solvent. The scandium source may be, for example, a leachate, an industrial byproduct, or a metal sludge, and will typically contain both scandium and iron ions, in addition to other metal ions.
Oct 10, 2002 A pilot-plant process has been developed based on an innovative laboratory-scale method for the recovery of scandium that exists in economically interesting concentrations in red mud, the main byproduct of alumina production.
