Polymer-fiber system that adsorbs uranium from seawater for yellowcake supply
Fluxnium's core product approach uses proprietary high-surface-area polymer fibers that passively adsorb dissolved uranium as seawater moves past them. Fibers are deployed on open-water longline systems similar to aquaculture infrastructure, then retrieved, processed into yellowcake, and redeployed. Public materials emphasize no mine tailings and a path toward cost-competitive domestic uranium supply.
