RARE EARTH ELEMENTS A REVIEW OF PRODUCTION, PROCESSING

Mining and processing activities have the potential to create a number of environmental risks to human health and the environment. The contaminants of concern will vary depending on the REE-mineral ore, the toxicity of the contaminants from the waste rock, ore stockpiles, and process waste streams. Rare earth elements (REEs) are a group
