In many scandium deposits, clinopyroxene is the main ore mineral, although in some deposits scandium is hosted by minerals that also concentrate the other REEs. As is the case for these other REEs, the main source of scandium is the mantle and the conveyors of scandium are alkaline igneous rocks (and carbonatites), including Alaskan …

for concentrating Sc in a specific phase and recovering Sc with high extraction efficiency. In this study, a two-stage innovative process was developed with an aim to extract scandium from a laterite ore. The first stage involves carbothermic reduction in which the iron is reduced at 1400–1600 °C and separated as a metallic phase,
In this study, reduction pre-treatment is conducted prior to the atmospheric leaching of limonitic laterite ore to produce a nickel-cobalt-scandium-rich leach solution and iron-rich magnetic residues. The leaching of pre-treated ore resulted in higher recovery of Ni, Co, and Sc when compared to the yield from the leaching of untreated ore.

The reserves of scandium oxide in the deposit are estimated to be > 40,000 tons. With the aid of EDS analysis and polarizing microscopy, samples of the ore were examined, and the different types of minerals containing scandium were identified together with their dissemi-nated features. The results reveal that the useful minerals for scandium pre-

The current study is based on the Crater Lake scandium deposit, which, to our knowledge, is the only deposit in a syenite complex with production potential and in which scandium is the principal ore metal. Hedenbergite is the main scandium mineral at Crater Lake, but subordinate proportions of scandium are also hosted by hastingsite.
Scandium ores with high scandium content can be recovered using pyro-metallurgical processes. The energy consumption, on the other hand, is substantial. Scandium is frequently enriched in residues, slags, tailings, and waste liquors and is primarily produced as a by-product of ore processing [21,22].
Scandium is one of the most highly abundant metals in the earth's crust, yet, it is not readily available for mining and extraction due to its dispersed nature. Scandium as an ore with a concentration greater …

Scandium rarely occurs as separate minerals in igneous rocks but is commonly incorporated into the structure of other minerals because it has an ionic radius of about 0.87 Å (Shannon 1976), much smaller than the other lanthanides, but similar to Mg 2+ and Fe 2+, which allows ready substitution into these sites in mafic minerals. Scandium …
