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 ...

Consumption of Cadmium 1 Introduction Cadmium is produced as a by-product from mining, smelting, and refining sulphide ores of zinc, and to a lesser degree, lead and copper. Cadmium minerals do not occur in concentrations and quantities sufficient to justify mining them. As it is a by-product of zinc, the production of cadmium is more
