DOW contains over 70 mineral nutrients and trace elements, including magnesium (Mg), calcium (Ca), and potassium (K) in their bio ionic form. To extract these products, DOW is treated with microfiltration and reverse osmosis to desalinate and concentrate magnesium, other minerals, and trace elements whilst eliminating the salt (sodium chloride ...
The magnesium chloride can be obtained using the Dow process, a process that mixes sea water and dolomite in a flocculator or by dehydration of magnesium chloride brines. The electrolytic cells are partially submerged in a molten salt electrolyte to which the produced magnesium chloride is added in concentrations between 6–18%. [44]
The Dow process may refer to: Dow process (bromine), a method of bromine extraction from brine; Dow process (magnesium), a method of magnesium extraction from brine; Dow process (phenol), a method of phenol production through the hydrolysis of chlorobenzene
The magnesium plant at Freeport operated until 1998, when Dow announced that it would not rebuild the unit following hurricane damage. [34] Because metallic magnesium is extracted from brine by an electrolytic process, the economics are sensitive to the cost of electricity.
The magnesium raw material of this type of reaction is magnesium oxide, which is obtained in many ways. In all cases, the raw materials must be calcined to remove both water and carbon dioxide. Magnesium oxide can also be obtained from sea or lake water magnesium chloride hydrolyzed to hydroxide. The Mg(OH) 2 is thermally dehydrated.

Magnesium chloride is an ionic compound, which can be electrolysed in a molten state to form magnesium and chlorine gas. The properties of magnesium bromide and magnesium iodide are similar. [ citation needed ] HMgX (X=Cl,Br,I) can be obtained by reacting the corresponding magnesium halide with magnesium hydride.
