#0183;#32;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:
Mar 28, 2020#0183;#32;Rare earth elements used to appear fairly close to the surface of the Earth, but humans have increasingly mined out accessible areas. As REEs become harder to extract, there is even discussion about mining them from the ocean floor.. But for now, REEs come from openpit mines.
Mining. The physical process of removing the ores from the ground is disruptive to the environment. Most rare earth elements are mined through open pit mining, which involves opening the surface of the earth using heavy equipment and machinery. Creating this disruption on the surface of the earth disrupts thriving ecosystems.
Processing rare earth minerals involves the separation and removal of uranium and thorium, which results in TENORM wastes. For detailed information and publications about rare earths, including statistics about domestic and international mining and use, see the Geological Survey Rare Earth Minerals Information page.
According to the USGS Rare Earths Report, the principal economic sources of rare earths are the minerals bastnasite, monazite, and loparite and the lateritic ionadsorption clays. The elements range in crustal abundance from cerium, the 25th most abundant element of the 78 common elements in the Earths crust at 60 parts per million, to
