Researchers from Ohio State University have demonstrated that a conceptual three-stage trap-extract-precipitate (TEP) process can successfully recover rare earth elements (REEs) from coal mine drainage (CMD). The team from Ohio State has been working closely with several key stakeholders in the region, including those from the public sector (Ohio Department of Natural Resources and City of Columbus), power generation industry (American Electric Power), and non-for-profit organizations (The Wilds).
