Scandium is present in most of the deposits of rare-earth and uranium compounds, but it is extracted from these ores in only a few mines worldwide. Because of the low availability and difficulties in the preparation of metallic scandium, which was first done in 1937, applications for scandium were not developed until the 1970s, when the ...
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 ...

Naturally occurring scandium (21 Sc) is composed of one stable isotope, 45 Sc. Twenty-seven radioisotopes have been characterized, with the most stable being 46 Sc with a half-life of 83.8 days, 47 Sc with a half-life of 3.35 days, and 48 Sc with a half-life of 43.7 hours and 44 Sc with a half-life of 3.97 hours.
World uranium reserves in 2010. Uranium reserves are reserves of recoverable uranium, regardless of isotope, based on a set market price.The list given here is based on Uranium 2020: Resources, Production and Demand, a joint report by the OECD Nuclear Energy Agency and the International Atomic Energy Agency.
The group is also called the scandium group or scandium family after its lightest member. The chemistry of the group 3 elements is typical for early transition metals: they all essentially have only the group oxidation state of +3 as a major one, and like the preceding main-group metals are quite electropositive and have a less rich ...
Abundance (atom fraction) of the chemical elements in Earth's upper continental crust as a function of atomic number; [5] siderophiles shown in yellow Graphs of abundance against atomic number can reveal patterns relating abundance to stellar nucleosynthesis and geochemistry.
