MINERAL COMMODITY PROFILES: CADMIUM
Cadmium was discovered in 1817 by Friedrich Stromeyer, who isolated it from an anomalously colored sample of zinc ore and named it "cadmium" after cadmeia, the ancient Greek name for zinc ore. It was first used as yellow cadmium sulfide paint pigment later in the 19th century. The first commercial cadmium metal was produced in Germany in the 1880s as a byproduct of the
