Environmental impacts of rare earth production MRS Bulletin
Rare earth elements (REEs) are important raw materials for green technologies. However, REE mining and production uses techniques that are often not environmentally sustainable. Life cycle assessment (LCA) is a well-recognized method for evaluating the environmental impacts of products and technologies. This article provides While rare earth minerals are now being touted as a key part of efforts to reduce greenhouse gases, there are environmental concerns in extracting these minerals from the ground, says an expert inRare earth minerals could help in climate change fight, but mining

Assessing the environmental footprint of the production of rare earth
Therefore, a holistic and comprehensive evaluation of environmental impacts associated with the rare earth metals and alloys production should be taken into account as the starting point to reduce the environmental destruction and the most widely-used approach is Life Cycle Assessment (LCA) (Evans et al., 2009; Golev et al., 2014; Over the past decade, China has supplied over 90% of global rare earths, and in doing so bore significant environmental burdens from processing its complex ores. 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.

Rare Earth Metals: Will We Have Enough? State of the Planet
All rare earth metals contain radioactive elements such as uranium and thorium, which can contaminate air, water, soil and groundwater. Metals such as arsenic, barium, copper, aluminum, lead and beryllium may be released during mining into the air or water, and can be toxic to human health. Moreover, the refinement process for rare The use of rare earth elements in various technologies continues to grow despite some alternatives being found for particular uses. Given a history of ecological concerns about pollution from rare earth mines, particularly in China, there are growing social and environmental concerns about the growth of the mining and mineral Social and Environmental Impact of the Rare Earth Industries

Rare earth elements are a nonrenewable and important strategic resource, and China is rich in these elements. However, the substantial exploitation of these resources has caused the migration1. Introduction. Rare earth elements (REEs) are termed the “vitamins” and “spice” of a modern economy (Dent 2012; Zepf 2013) because adding small quantities of REEs to metals substantially improve the latter's properties.REEs consist of seventeen elements that are commonly added to elements like iron and boron, to produce materials Geopolitics and rare earth metals ScienceDirect

Rare Earth Elements Pose Environmental, Economic Risks for Clean
On today’s podcast we’ll look at the market for rare earths, explain why they’re so important to clean energy, and discuss the growing calls to diversify the world’s rare earth supply. We’ll also talk about the dirty underside of rare earths, the mining and processing of which can be environmentally destructive in the extreme.The current global rare-earth element (REE) supply chain is highly imbalanced and tightly controlled by just a few countries. Such an imbalance of the critical metals supply chain poses a significant challenge to the energy-transition strategies and the national security of many countries.
