Artificial sand, also known as manufactured sand, is a substitute for natural sand. The sand is produced by crushing rocks, quarry stones or larger aggregates into finer granules, with the help of machines. The artificial sand is a more reliable alternative to natural sand, which has become scarce and expensive due to excessive demand.
Manganese (Mn) is the twelfth most abundant element in the Earth's crust. Amongst some 300 minerals containing manganese, only about a dozen are of economic significance.
