Environmental Considerations When Refining Mining And Recycling Rare Earths

Environmental Damage. 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 disposal. All of the stages of mining, refining, and disposal come with
