Cadmium: processingMetalpedia

Cadmium is mainly a byproduct of beneficiating and refining of zinc metal from sulfide ore concentrates. Refining of zinc and its cadmium content, can be accomplished by treating the zinc concentrates and/or zincbearing secondary materials using either a hydrometallurgical or pyrometallurgical process.

Zinc processing |

The separation of metallic zinc from its ores by pyrometallurgy is much more difficult than with other common metals, such as copper, lead, and iron, because the reduction of zinc oxide by carbon (C) proceeds spontaneously only above the zinc boiling point of 907 °C (1,665 °F). Efficient methods of condensing the vapour to liquid metal were not discovered until the 14th century.

Lead University of Denver

First of all, the ore must be concentrated to separate the lead ore from the zinc ore, for example. It turns out to be possible to do this with flotation. A substance is added that wets the zinc ore, allowing it to sink to the bottom, but does not wet the galena, allowing it to be caught up in a that floats on the surface of the water.
