Identification and Description of Mineral Processing

Cadmium is mainly a byproduct of the production of zinc metal from sulfide ore concentrates. The mined zinc ores are crushed and ground to liberate the zinc sulfide particles from the waste host rock. The ground ore is usually treated by a differential flotation process to separate the zinc-bearing particles from the waste rock, yielding a high-grade

Cadmium Statistics and Information USGS

Cadmium Statistics and Information Cadmium, a soft, malleable, ductile, bluish-white metal, was discovered in Germany in 1817, and Germany remained the only important producer for 100 years. Currently, a large percentage of global cadmium metal production takes place in Asia. Cadmium is generally recovered as a byproduct from zinc concentrates.

Cadmium Assignment Point

Commercial production of cadmium ore depends on the mining of zinc. Some zinc ores concentrates from sulfidic zinc ores contain up to 1.4% of cadmium. It is commercially available as an oxide, chloride, or sulfide. Cadmium metal (Cd 2+) refined from the ore is a silver-white, blue-tinged lustrous heavy metal solid at room temperature.
