1. Introduction. The fast development of modern technologies has led to the constantly growing demand for rare earth metals (REMs). This expression refers to the group of 17 elements in the periodic table, from lanthanum (atomic number 57) to lutetium (atomic number 71), that can be found in nature in the form of compounds, except for promethium, which is obtained by synthetic methods (Massari ...
Environmental Damage - MIT
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 ...

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:
Environmental Impacts of Rare Earth Mining and …
Neodymium and dysprosium are two rare earth elements (REEs), out of a group of 17 elements. Due to their unique properties, REEs gained increasing importance in many new technologies, like wind turbines, batteries, etc. However, the production of REEs requires high material and energy consumption and is associated with considerable environmental burdens.
Rare Earths from Mines to Metals: Comparing …
In this study, we used life cycle assessment to quantify environmental impacts for producing 1 kilogram (kg) of 15 rare earth elements from each major production pathway. The scope of assessment included the largest rare earth oxide (REO) production chain in Bayan Obo, as well as lesser known production chains for bastnäsite in Sichuan and in‐situ leaching of kaolin clays in the Seven ...
