 · Magnesium was first recognized as an element in 1755 by Joseph Black. However, it wasn't isolated until 1808 by Sir Humphry Davy. The most common commercial use of magnesium metal is as an alloying agent with aluminum. The resulting alloy is lighter, stronger, and easier to work than pure aluminum. China is the leading producer of magnesium, responsible for about 80% of the world's .

As magnesium carbonate is relatively soluble (approximately 70 mg·L –1), an excess of lime will lead to the following reaction: And if amounts of reagent are precisely adjusted, the water's alkalinity will be reduced to the theoretical solubility applicable to the CaCO 3 + Mg (OH) 2 system which ranges from 2 to 3°F under normal temperature and concentration conditions. However, this ...
