The goal is to extract magnesium hydroxide from the seawater, not the elemental magnesium. The seawater is concentrated into brine and then dried and dissolved in hydrochloric acid. The reaction creates magnesium chloride, which is evaporated to produce a salt.
Dolomite is a calcium carbonatemagnesium carbonate mineral (CaCO 3CMgCO 3) that has a theoretical magnesium content of 22 percent. Brucite, magnesium hydroxide [Mg(OH) 2], contains up to 69 percent magnesium, and olivine (Mg 2Fe 2SiO 4) contains up to 19 percent magnesium. Of these minerals, magnesite and dolomite are the largest sources of ...

(Calcium Carbonate, magnesium hydroxide). However some known impurities contained in the mud, particularly chromium(VI) compounds are toxic.
When dolomite is crushed, roasted and mixed with seawater in large tanks, magnesium hydroxide settles to the bottom. Heating, mixing in coke, and reacting with chlorine, then produces molten magnesium chloride. This can be electrolyzed, releasing magnesium, which floats to the surface.
