Cadmium - Wikipedia
Cadmium makes up about 0.1 ppm of Earth's crust. It is much rarer than zinc, which makes up about 65 ppm. No significant deposits of cadmium-containing ores are known. The only cadmium mineral of importance, greenockite (CdS), is nearly always associated with sphalerite (ZnS). This association is caused by geochemical similarity between zinc and cadmium, with no geological proces

Cadmium: Production, Properties, Applications and Effect
Cadmium is primarily produced as a by-product of zinc production done through smelting, mining, and refining. It can also be obtained as aby-product of lead and copper production but in very small quantities. Recycling accounts for about 18% of cadmium production. Direct cadmium production is popular in Asia while it’s on decline in Europe.
