The world production of scandium is in the order of 15–20 tonnes per year, in the form of scandium oxide. The demand is slightly higher, [ 23 ] and both the production and demand keep increasing. In 2003, only three mines produced scandium: the uranium and iron mines in Zhovti Vody in Ukraine, the rare-earth mines in Bayan Obo , China, and ...
An overview of one of the regolith-hosted rare earth element deposits (a type of Rare Earth Element mine) in South China [1]. Regolith-hosted rare earth element deposits (also known as ion-adsorption deposits) are rare-earth element (REE) ores in decomposed rocks that are formed by intense weathering of REE-rich parental rocks (e.g. granite, tuff etc.) in subtropical areas.

That mine may be able to produce as much as 7200 metric tons of ferro niobium and 95 metric tons of scandium trioxide annually, [86] although, as of 2022, financing is still in the works. [ 83 ] In the UK, Pensana has begun construction of their US$195 million rare-earth processing plant which secured funding from the UK government's Automotive ...

Scandium oxide is the primary form of refined scandium produced by the mining industry. Scandium-rich ores, such as thortveitite (Sc,Y) 2 (Si 2 O 7) and kolbeckite ScPO 4 ·2H 2 O are rare, however trace amounts of scandium are present in many other minerals. Scandium oxide is therefore predominantly produced as a by-product from the extraction ...
Ukraine also possesses substantial reserves of scandium (as a byproduct of iron ore processing), [14] titanium (as both ilmenite and rutile), [15] zirconium [16] and mercury. [17] Mercury mining and processing by the Nikitovka Mines in Horlivka ceased in 1991 and the mine equipment has been partially converted for fluorescent lamp recycling ...
It employed about 22,000 people in mining, beneficiation, metallurgy, power generation, and auxiliary production. The company was established in 1997 through the merger of eastern Kazakhstan's three main nonferrous metals companies—Leninogorsk (now Ridder) Polymetallic complex, Ust-Kamenogorsk Lead and Zinc complex, and Zyryanovsk Lead
