Cadmium Minerals Education Coalition.Cadmium minerals are very rare and include cadmoselite cadmium selenide, greenockite cadmium sulfide and otavite cadmium carbonate. Cadmium substitutes for zinc in sphalerite, so most is recovered during the processing of zinc ores. It is produced in most zinc-smelting countries of the world.

Cadmium resources reserves and productionMetalpedia.Cadmium is usually produced as a byproduct in the recovery of primary zinc from zinc ores, and also from some lead ores or complex copper - lead - zinc ores. However, it is generally agreed that the cadmium in lead and copper ores is associated with the zinc sulfide present rather than with the other minerals. World cadmium resources.
