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.
