Our Separation and Metallization technologies give the U.S. control over critical metals by refining tailings into rare earth elements used in EVs, defense systems, and modern electronics.
By combining electrochemistry and advanced materials science, we recover critical metals from overlooked sources and refine them at scale.
Feedstock
We source overlooked mining byproducts that still contain valuable metals.
Extraction
We extract critical metals from tailings and recycled materials, using what others leave behind.
Separation
Our proprietary technology separates individual light and heavy rare earth oxides from ores and concentrates, scaling efficiently, and economically.
MetalLization
Our breakthrough stabilized chemistries and automation transform rare earth oxides into pure metals and alloys —safely, economically, and without waste.
End Use
Our metals support tech, defense systems, batteries, advanced manufacturing and more.
Building our future
America needs rare earth refining to power its future. Phoenix Tailings has built it. Our facilities are the foundation of a new, resilient supply chain.
