The list of environmental concerns that can be connected with rare earth elements is not a brief one. Throughout the cycle of mining processes that rare earth elements go through, there is potential for negative effects on the environment. Extracting rare earth elements begins with mining. This is followed by the refining process, and then ...
The impact of mining and smelting of metal ores on environmental quality is described. Mines produce large amounts of waste because the ore is only a small fraction of the total volume of the mined material. In the metal industry, production of Cu, Pb, and Zn causes the greatest degradation of the environment.
