Zinc | Geoscience Australia
Gravity and magnetic separation methods were unsuccessful but in 1901 a new metallurgical process, called flotation, was devised at Broken Hill which achieved recoveries of the zinc minerals from ore upwards of 60%. After considerable experimentation, a selective flotation method which worked on a commercial scale was …

Cadmium (Cd)
The process involves several key steps to extract Cadmium from these base metals: Mining and Concentration: Zinc ores, which also contain other metals such as lead, copper, and Cadmium, are mined and then concentrated by crushing the ore and flotation techniques. This concentration increases the zinc content to about 50-60%.

Removal of cadmium (II) from simulated wastewater by ion flotation
The removal of cadmium ions by ion flotation process is very sensitive to the ionic strength. So the ionic strength of wastewaters must be decreased by an acid (such as H 2 SO 4) before flotation. Subsequently, the application of ion flotation for cadmium ions removal from aqueous dilute solutions seems to be efficient.
