Simple Process Extracts Valuable Magnesium Salt From Seawater
9/23/2022
Since ancient times, humans have extracted salts, like table salt, from the ocean. While table salt is the easiest to obtain, seawater is a rich source of different minerals, and researchers are exploring which ones they can pull from the ocean. One such mineral, magnesium, is abundant in the sea and increasingly useful on the land.
