Cadmium resources, reserves and production-Metalpedia

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.

Some lead ores also contain small quantities of cadmium, and, if it is present in sufficient quantity, it is recovered by a cycle of operations similar to that used by zinc smelters. Zinc producers who use the electrolytic process recover cadmium in a somewhat different way, but again the principle is the same, beginning with the roasting of ...

2021-11-18  Cadmium is a metal that appears soft, malleable, and bluish-white in its elemental form. While it is a relatively widespread element, it is rarely found on its own as a pure metal and more often forms complex compounds in zinc ores. It is mainly produced through the process of smelting, mining, and refining zinc, lead, and copper.

Pure cadmium is a bluish-white metal but does not occur as such in nature. It was first discovered in 1817 by a German chemist, F. Stromeyer, as a constituent of the zinc ore smithsonite (ZnCO 3). Cadmium is mainly found in zinc, lead-zinc and lead-copper-zinc ores,

2014-11-15  Cadmium has the capability to bind with cystein, glutamate, histidine and aspartate ligands and can lead to the deficiency of iron (Castagnetto et al., 2002). Cadmium and zinc have the same oxidation states and hence cadmium can replace zinc present in metallothionein, thereby inhibiting it from acting as a free radical scavenger within the cell.
