Non-desirable elements are removed by selective precipitation, and the working solution is conditioned for use in the reactor. The pH is adjusted to prepare the solution.

A non-uniform magnetic field creates high- and low-intensity zones close to an electrode within the solution. The most magnetic REEs concentrate in the high-field zone, and the electroreduction of nitrate ions locally raises the pH, selectively precipitating the target REEs.

After processing the precipitate is recovered, and undergoes additional purification cycles if needed, to achieve the required purity levels.

The full process is engineered to fit inside a standard 40-foot shipping container. This modular format enables rapid on-site deployment — next to a mine, a magnet factory, or a recycling centre — cutting transport costs and logistics emissions. Delivering >60% OPEX reduction and >40% CAPEX reduction versus conventional technologies.
