Scandium Metal

Scandium is a typical dispersed lithophile element, but it is not rare. Its average abundance in the crust is 22-30 PPM (i.e. 22-30 g/t, converted to 35-48 g/t scandium trioxide), much higher than Ag, Au, Pb, Sb, Mo, Hg, W and Bi, and comparable to the abundance of B, Br, Sn, Ge and As.
