About
Tidal Metals has developed an efficient, scalable solution for accessing the estimated two billion megatons of magnesium dissolved in our oceans — enough to last millennia. Powered by electricity from renewable sources, our “clean and green” method concentrates and extracts magnesium salt in seawater using proprietary innovations and established physical processes. Nothing is added to the water, and no waste is generated.
