Rare Earth Technologies, Inc. (RETi)

Rare Earth Technologies, Inc. (RETi) is a privately held U.S. critical-minerals company headquartered in Cincinnati, Ohio, that specializes in the separation, refining, and purification of rare-earth elements (REEs). Founded in 2021, RETi has developed a proprietary continuous chromatography and column-chemistry process capable of achieving up to 99.999% purity in a single pass, separating mixed rare-earth oxides from both mined ore and recycled permanent-magnet feedstocks. The technology targets magnet-critical elements such as neodymium, praseodymium, dysprosium, and terbium used in electric vehicles, electronics, wind turbines, and defense systems. Positioned in the midstream refining segment of the supply chain, RETi aims to establish one of the first American-based commercial rare-earth refining facilities, supporting a cleaner, faster, and more economical domestic alternative to Chinese processing and strengthening Western critical-mineral supply-chain independence.
