Introduction
| Greenockite consists of cadmium and sulfur. Sometime, zinc replaces cadmium, and forms a solid solution series. The mineral with more cadmium is greenockite, and the one with more zinc is wurtzite, dimorphous with hawleyite. Greenockite fluoresces orange yellow under ultraviolet light if it contains a minor amount of zinc. Cadmium minerals are rare, the best-known of which is mineral greenockite. However, greenockite reserves are not common in the world and scanty in production. Mineral greenockite is a source of cadmium, and oftentimes associated with sphalerite. |
