Cadmium (Cd) is a soft, malleable, bluish white metal found in zinc ores, and to a much lesser extent, in the cadmium mineral greenockite. In 2011, U.S. production of cadmium was estimated at 600 metric tons, down approximately 40% from the production levels 20 years ago (1992). Most of the cadmium produced today is obtained from zinc byproducts and recovered from spent nickel-cadmium batteries.

Extraction of Cadmium Screening studies indicated that Primene JM-T, Alamine 336, Aliquat S can remove more than 95 percent of the cadmium from synthetic solu- tions with a single extraction. Of the three reagents, Alamine 336 appear- ed to be superior and was chosen for further investigations.

Methods used for Cd separation and recovery including pyrometallurgical, solvent extraction, and bioleaching are expensive and inefficient [13]. The need for economic and environmentally friendly processes to separate and recovery Cd and Ni from these spent batteries has been observed [13].

Exposure and Controls. Workers can be exposed to cadmium by breathing in dusts, fumes, or mists containing cadmium. Cadmium or cadmium compounds can also get on the skin, contaminate clothing or food, and be ingested (which is also one of the routes of exposure).The most effective way to prevent exposure to a hazardous metal such as cadmium is through elimination or substitution.
