Cyclic Materials recovers rare earth elements and critical minerals from end-of-life products, building a circular supply chain through 'urban mining'. Using proprietary MagCycle magnet separation, REEPure hydrometallurgical refining, and metallization technologies, it produces recycled rare earth oxides and metals including neodymium-praseodymium (NdPr), terbium (Tb), and dysprosium (Dy), while also recovering copper, aluminum, and clean ferrous materials.
