Rare earth mining poses toxic risks Aliran
2020-12-23 The mining of REEs has caused contamination of soil and water. Radioactive waste can leach out into aquatic environments and be absorbed by aquatic vegetation, which can then bioaccumulate and potentially enter the human chain if livestock or humans choose to eat the vegetation. Exposure to radioactive waste can lead to cancer, respiratory

Rare Earth Elements: A Resource Constraint of the Energy
2021-5-18 Rare earth elements are widely distributed throughout the earth’s crust, but generally in low concentrations. The concentration of individual REEs depends on the type of mineral deposit being mined, and REEs are often found alongside radioactive elements such as thorium and uranium (Rhodes 2011).

Recycling of the rare earth elements ScienceDirect
2018-10-1 The rare earth elements (REE) are vital to modern technologies and society and are amongst the most critical of the critical elements. Despite these facts, typically only around 1% of the REE are recycled from end-products, with the rest deporting to waste and being removed from the materials cycle.
