Cadmium minerals do not occur in concentrations and quantities sufficient to justify mining them in their own right, but they are present in most zinc ores and are concentrated during zinc ore processing. Cadmium is a byproduct of the extraction and refining of zinc metal from zinc sulfide ore concentrates. ... B. Cadmium Refining The ...
Cadmium. Cadmium (Cd), a toxic heavy metal considered a hazardous substance, is a waste byproduct of mining, smelting and refining sulfidic ores of zinc during zinc refining, and therefore its production does not depend on PV market demand. CdTe PV modules provide a beneficial and safe use for cadmium that would otherwise be stored for future ...
