Who We Are Looking For: 

Phoenix Tailings is looking for a Mineralogist with hands on experience in rare earth element-bearing minerals and their associated gangue. You’ll play a pivotal role in helping us unlock and optimize REE extraction pathways from unconventional sources like industrial waste and tailings. Your mineralogical insights will directly shape our clean, scalable recovery technologies and accelerate the availability of REEs vital to electrification, defense, and advanced manufacturing.
