EPA - Identification and Description of Mineral Processing ...

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

The separation of cadmium from zinc with a synergistic ...

Jul 01, 2005· This suggests that Cd could be separated from zinc better with an A / O ratio of 1.5 : 1. The distribution isotherms of cadmium and zinc and a McCabe–Thiele diagram indicating the required number of theoretical extraction stages at an A / O ratio of 1.5 : 1 are shown in Fig. 4. Only 2 stages would be required to extract nearly 99% Cd.

Sulfide Precipitation. The addition of a sulfide induces precipitation of dissolved metals as metal sulfides. This treatment is very effective for many metals, including zinc and cadmium. It is less effective for some contaminants such as manganese. If the MIW is acidic, pH adjustment may be required prior to the sulfide precipitation.
