Rare earth recovery is the process of extracting and recycling valuable rare earth elements from electronic waste, industrial byproducts, and other sources. Rare earth elements are crucial components in many modern technologies, including smartphones, electric vehicles, and renewable energy technologies. Due to their limited global supply and environmental impact of mining, efforts are being made to develop efficient methods for recovering and reusing rare earth elements to reduce dependency on new mining and promote sustainability. Research in this area focuses on developing cost-effective and environmentally friendly techniques for recovering rare earth elements from various sources, as well as studying the potential risks and benefits of widespread rare earth recycling.
