Our  History

Rare Earth Salts (RES) was founded by Dr. Joseph Brewer in 2012 to address the need for inexpensive and sustainable Rare Earth Element (REE) separation process.


RES has developed a patented technology for separation and refining of all REE's to high purity from various feedstocks worldwide both ore-based and circular based concentrate.

Over 60 different feedstock materials evaluated and analysed.


First commercial sale at scale completed in 2020 – 17.5 MT Lanthanum @ 99.99% purity.

Successfully separated Europium Oxide and Yttrium Oxide @ 99.99% purity in 2021.

Successfully separated NdPr oxide to 99.55% purity in 2022.


RES is targeting three* of the BIG 4 REE's (NdPr*, Tb*, Dy) used for magnets, as they have the highest commercial value.


We also produce co-products alongside these minerals.
