Cadmium, a naturally occurring element found in the earth's crust, was discovered in 1817, but was not used commercially until the end of the 19th century. This soft, silver-white metal was …
The techniques used in cadmium mining follow those of zinc mining, since cadmium is generally extracted as a byproduct. The process typically involves open-pit or underground mining of the …
Although Cd is widely used in industry, it poses threat to human health, as it is easy to accumulate in the food chain. It is well known that food is the main source of Cd intake for non-smokers (Zou, Zhou, Zhou, Jia, & Guo, 2021).Cd contained in soil and water can be absorbed by certain crops and aquatic organisms and accumulate in the food chain (WHO, …
Cadmium is mainly a byproduct of beneficiating and refining 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.
Overview. Cadmium is an element that is widely distributed in the Earth's crust (soil and rocks), air and water. Cadmium also exists as several compounds due to it combining with other elements ...
