Smithsonite: The mineral smithsonite information and picturesSmithsonite occurs in a wide variation of colors. Its typical globular habit and often vibrant colors make this a desirable mineral for collectors. Smithsonite is composed of zinc carbonate, but the zinc may be partially replaced with other elements. Those elements are responsible for the color variations.

Cadmium resources, reserves and productionMetalpediaCadmium's abundance in the Earth's crust is about part per million (ppm). Greenockite (CdS), the only cadmium mineral of importance, is not found in any isolated deposits, but is nearly always associated with sphalerite (ZnS). Cadmium is usually produced as a byproduct in the recovery of primary zinc from zinc ores.
