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 ...
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 ...
The rare-earth elements (REE), also called the rare-earth metals or rare earths, and sometimes the lanthanides or lanthanoids (although scandium and yttrium, which do not belong to this series, are usually included as rare earths), [1] are a set of 17 nearly indistinguishable lustrous silvery-white soft heavy metals.

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 ...
For advanced industrial economies the commonly used terms "critical minerals" or "critical raw materials" refer to materials required for their strategic industries where there is a risk of interruption to supply. [5]
The new mines included the Artemovskoye (which was part of the East Region complex), which was completed ahead of schedule and had the capacity to produce 28,000 t/yr of copper and 98,000 t/yr of zinc; the Zhaman-Aybat (which was part of the Zhezkazgan mining-metallurgical complex), which was under construction and has reserves of 75.3 Mt of ...
Using the Federal Reserve’s $2.3 trillion M0 currency figure and a current world population of 8.17 billion, per Worldometer, there’s about $282 per person in the world, on average. Using the ...
