Recover Precious Metals,
Rare Earths, and Critical Minerals
Open-source electrochemical recovery for ore, e-waste, tailings, and industrial waste.
SEM TECH, our open-source Salt Electro Mining Technology, uses saltwater and electricity to recover precious metals, rare earths, and 53 of the 60 US critical minerals. Closed loop, up to 99% recovery at costs as low as $50 a ton, while cleaning heavy metal pollution out of the environment.

Local Business
Based in Florida, USA, we’re building a fully domestic precious metal industry, keeping critical operations local and independent.
Eco Sustainability
Driven by both economic and environmental priorities, we’re building regenerative systems that reduce reliance on additional chemical inputs.
Updates
Regular YouTube updates that transparently share progress, lessons learned, and practical knowledge to prove continued development of the technology.
Competitive
Extracts 53 of the 60 US critical minerals in one leaching solution, supports onsite acid regeneration, and runs at costs as low as $50 a ton.
Our Services
Analysis
By combining our electrochemistry platform with lab grade XRF instrumentation (Rigaku NEX DE spectrometer) our team can detect and evaluate elements that most others overlook or aren’t able to measure.

Extraction
Our closed-loop electrochemistry system can process a wide range of feedstocks. Raw soil, e-waste, and industrial waste, producing a clean output and concentrated high value product. All continuously regenerating the acids into a clean output stream.

Separation
We can selectively purify each element in-house to the customer’s final specification, with custom requirements handled through a single, continuous operation: eliminating the need for additional outside companies or processors.

We make waste clean economically
Building an industry from scratch is difficult, and today the United States has little domestic capacity for critical minerals and platinum group metals. Much of the world’s rare earth extraction and processing is concentrated in Asia and Africa. Our mission is to change that by creating pathways for organizations of all sizes from startups to large enterprises to access these markets and help meet U.S. and global supply needs.
Additionally, our eco-friendly approach unlocks feedstocks that have largely gone untapped, whether in regions where extraction has been halted due to pollution concerns or at legacy waste and dump sites containing “unrecoverable” critical minerals. Our technology can remediate heavy metals while producing a profitable, high-value product, creating a true win-win for communities, regulators, and industry.
“Everyone wants to change the world but no one wants to try.”
We decided to try.
