Extracting or finding, magnesium from or in housewhole products like, toys, milk of magnesia, epsom salt, and other things.
Green vegetables such as spinach provide magnesium because the center of the chlorophyll molecule contains magnesium. Nuts, seeds, and some whole grains are also good sources of magnesium. Although magnesium is present in many foods, it usually occurs in small amounts. As with most nutrients, daily needs for magnesium cannot be met from a single food. Eating a wide variety of foods, including five servings of fruits and vegetables daily and plenty of whole grains, helps to ensure an adequate intake of magnesium. The magnesium content of refined foods is usually low (4). Whole-wheat bread, for example, has twice as much magnesium as white bread because the magnesium-rich germ and bran are removed when white flour is processed. The table of food sources of magnesium suggests many dietary sources of magnesium. Water can provide magnesium, but the amount varies according to the water supply. Hard water contains more magnesium than soft water. Dietary surveys do not estimate magnesium intake from water, which may lead to underestimating total magnesium intake and its variability. Eating a wide variety of legumes, nuts, whole grains, and vegetables will help you meet your daily dietary need for magnesium.
If you want to take magnesium just buy the supplements.
This is a qualiative method to extract magnesium, other metal impurities may be extracted during the process Well, we need A LOT of sea water first. Add base (calcined dolomite) to sea water, filter out any precipitate. Add acid (HCl or H2SO4) to the precipitate, filter out any undissolved precipitate, keep the filtrate. Finally, electrolyze the filtrate, the process does use large amounts of energy (Electrolysis alone approx 18 kWhe/kg magnesium); also, toxic chlorine gas might be formed during the possess. Another potential magnesium route would be to add slaked lime to sea water (or better yet desalination concentrated brine) to produce magnesium hydroxide . Then roast to form magnesium oxide. the Magnesium oxide could then be thermally reduced with Ferrosillicon using the Pidgeon process.
