Magnesium is a critical industrial metal with structural properties similar to steel and aluminum, but weighing 75% less than steel and 33% less than aluminum. The problem is that most of the global magnesium supply comes from China, where it’s mined and refined using outdated, toxic, and carbon-intensive processes. Tidal Metals has patented a clean, efficient way to extract magnesium from seawater — where it’s the second most prevalent metal, after sodium — using filtration, crystallization, dehydration, and electrolysis. As the process harvests magnesium from ocean waters and brines, Tidal Metals will deliver abundant “green magnesium” for industries such as automotive, aerospace, and defense.
