Potential dangers of mining rare earth metals
· Rare earth metals are used in wind turbines, also, which means that even though clean energy is generated, the use of these toxic metals makes the green energy impure. Rare earth metals mining generate a lot of radioactive waste which is dangerous for both humans and the environment. Take a look at the potential dangers of mining rare earth metals:
Why China's stranglehold on rare minerals could cost the earth

Mines, Minerals, and "Green" Energy: A Reality Check
· For rare earths, some 20 to 160 tons of ore are mined per ton of element. For cobalt, roughly 1,500 tons of ore are mined to get to one ton of the element. In the calculus of economic and environmental costs, one must also include the socalled overburden—the tons of rocks and dirt that are first removed to get access to often deeply buried mineralbearing ore.

concentrate, which is further processed to separate REEbearing minerals (such as bastnaesite). The next phase in the value chain is separation and purifiion of REEbearing minerals into their pure oxide form, r are earth oxide. Rare earth oxides can be standalone products; however, market demand dictates their conversion into metals.

· Rare Earth Production Outside of China. Mines in Australia began producing rare earth oxides in 2011. In 2012 and 2013 they were supplying about 2% to 3% of world production. In 2012 the Mountain Pass Mine came back into production, and the United States produced about 4% of the world's rare earth elements in 2013.
Resources Technology and Critical Minerals Processing
Critical minerals processing covers businesses and enterprises associated with processing critical minerals for use in value added manufacturing and manufacturing products using those refined materials. Using the battery value chain as an example, this can be from processing lithium ore into lithium hydroxide or metal, through to battery assembly.
