articleosti6894652, title Cadmium a trace element of concern in mining and manufacturing, author Cox, D B, abstractNote The trace element cadmium is reviewed in terms of natural and industrial sources, airborne levels throughout the United States, the metals presence in waters, plant uptake, cadmium levels in shellfish, and adverse human effects.
Cadmium is also found in meat, especially sweetmeats such as liver and kidney. In certain areas, cadmium concentrations are elevated in shellfish and mushrooms Jarup 2002. Cadmium can also enter the food chain from water. In Japan, zinc mining operations contaminated the local water supplies with cadmium.
Cadmium has many chemical similarities to zinc and is often recovered from the primary zinc ore sphalerite. The single most important use of cadmium is in the production of nickel-cadmium Ni-Cad batteries. Relation to Mining. Cadmium rarely appears in nature and is most commonly sourced by its removal from zinc metals during the refining process.
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.

May 17, 2017 May 17, 2017 Ive been mining a rocky ring, found plenty of common materials, but not cadmium yet, no rare materials. In this video, Kornelius says common materials can be mined from asteriods but not rare materials, although he doesnt sound too sure, asks people to tell him if they found cadmium.
Abstract. Paddy rice has been likened to nictiana sp in its ability to scavenge cadmium Cd from soil, whereas arsenic As accumulation is commonly an order of magnitude higher than in other cereal crops.
