Zinc-to-cadmium ratios in typical zinc ores range from 200:1 to 400:1. Sphalerite (ZnS), the most economically significant zinc mineral, commonly contains minor amounts of other elements; cadmium, which shares certain similar chemical properties with zinc, will often substitute for zinc in the sphalerite crystal lattice.

Cadmium Used by Van Gogh, Edison and Junger. Cadmium is present throughout the environment and is naturally occurring in both the Earth's water and crust. It was first isolated in Germany in 1817 as a by-product of zinc refining. It found use in the 1850's as a pigment used in paintings because of its brilliant yellow, orange, and red colours.
