RARE EARTH SALTS was founded by Dr. Joseph Brewer to address the global need for a cost-effective, sustainable, and environmentally friendly rare earth element separation process. RARE EARTH SALTS has developed proprietary, patented technologies for the separation and refining of rare earth elements to high purity from various feedstocks worldwide, both ore-based and recycled material.

RARE EARTH SALTS has developed commercial processes to produce three of the “BIG 4” most critical rare earth oxides: Neodymium, Praseodymium, and Terbium; and is also producing Cerium, Lanthanum, Europium and Yttrium.

RARE EARTH SALTS has worked closely with the U.S. government, including the Department of Defense and Department of Energy.

RARE EARTH SALTS is the only heavy rare earth element separation company in the world outside of Asia.

RARE EARTH SALTS' 50,000-square-foot headquarters, commercial demonstration plant, laboratory, and research & development facility are in Nebraska, the heartland of America.
