Cadmium - GreenFacts

2020-4-1 · Cadmium is produced mainly as a by-product of mining, smelting and refining of zinc and, to a lesser degree, as a by-product of lead and copper manufacturing. Most of the cadmium produced is used in the production of nickel-cadmium batteries, which in 2004 represented 81 per cent of the total amount of cadmium.

Characterization of Zinc, Lead, and Cadmium in Mine

2019-5-25 · We characterized the lability and bioaccessibility of Zn, Pb, and Cd in size-fractionated mine waste at the Tar Creek Superfund Site (Oklahoma) to assess the potential for metal transport, exposure, and subsequent bioavailability. Bulk mine waste samples contained elevated Zn (9100 ± 2500 ppm), Pb (650 ± 360 ppm), and Cd (42 ± 10 ppm), while particles with the greatest potential for wind ...

Chemistry and occurrence of cadmium and zinc in

Zinc solubility may also be controlled by silicate in some waters. Biological factors and Sorption by stream sediments may also be significant controls. Concentrations of cadmium above 10 μg/l may be stable in water having low total solute concentrations and pH and can be difficult to remove by conventional water treatment processes.
