How is magnesium made from salt water?

260 views

I’m writing a book and part of it involves an alchemist making magnesium from sea water but I don’t understand the actual process enough to come up with an old-timey, semi-magic equivalent.

I didn’t take chemistry past tenth grade so all the videos and articles online make no sense to me after a paragraph or a minute.

Salt water contains a variety of chemicals (namely salts) and some of those chemicals (again, salts) contain magnesium. All you have to do is separate out the magnesium salts, and then separate the magnesium from whatever its bonded to.

A salt is just a metal ionically bonded to a non metal. NaCl is table salt, but it is only one type of salt.
