Production Process of Scandium Oxide

What’s Scandium Oxide powder?

The most significant product in scandium products is the Scandium Oxide. The physical and chemical characteristics of Scandium oxide are identical to that of rare earths oxides. Therefore, production processes are very similar. Sc2O3 may produce metal scandium and other scandium alloys under certain environmental conditions. Scandium oxide has many uses in aerospace, aluminum alloys, electric light source and lasers as well as ceramics and ceramic activators.

Scandium Resources in Nature

Scandium is found in approximately 800 different minerals. There are very few scandium-containing mineral species, mostly due to the interaction with other minerals. You can find many minerals that are scandium-containing, including ilmenite and rare earth ores, wolframite as well as vanadium-titanium magneticite, rare Earth iron ore, manganese depleted ore, ilmenite and bauxite. The mine has the greatest amount of scandium.

Materials Used in the Production of Scandium Oxide Powder

Scandium oxide raw materials are mostly scandium-containing water, waste residue, and soot from metallurgy. Also, scandium concentrate is obtained following the beneficiation vanadium–titanium magite.

1. The majority of the tungsten-extracted waste is contaminated with scandium. Scandium oxide 0.05%) can be found in the original ore of wolframite. Scandium oxide is 150600 g/t after the extraction. Pretreatment involves dissolving the waste in hydrochloric acids. The resulting ScCl3 solution then becomes the raw material to obtain scandium oxide.
2. A waste liquid containing scandium (mainly after the extraction of titanium form ilmenite) is considered to be a “scadium-containing” fluid. Scandium oxide 15-20g/m3 is the primary raw material to extract scandium dioxide from ilmenite.
3. Scandium-containing soot is mainly the soot that has been chlorinated to sponge titanium. Pretreatment of the soot results in acid-dissolved scandium liquid, which is used as the raw material to extract scandium oxide.
4. Scandium concentrate, mainly from scandium magnetite beneficiation. Sc 27g/t of vanadium magnetite is present, while Sc 112-114g/t can be found in the beneficiated scandium concentrate. ScCl3 is obtained by dissolving the scandium concentrate in hydrochloric acids. It is used as raw material to extract scandium dioxide.
