The physical properties of scandium include its lightweight and malleability. It is also a low-melting point element, with a melting point of 1,541°C (2,816°F). Its density is 2.99 g/cm3, and it has an atomic weight of 45. The chemical properties of scandium are what makes it an interesting material to work with.

During the scandium oxide production, the beneficiation stage contributes around 88% of the overall impact (Fig. 3 a). The main processes affecting the potential environmental impact in the beneficiation stage are Fe separation (II) (30%), and Fe separation (III) (20%), both of which account for more than half of the total impact.
