Zirconium is a chemical element with the symbol Zr and atomic number 40. The name zirconium is taken from the name of the mineral zircon (the word is related to Persian zargun (zircon; zar-gun, "gold-like" or "as gold")), the most important source of zirconium. It is a lustrous, grey-white, strong transition metal that closely resembles hafnium and, to a lesser extent, titanium.

Zircon Mining. Mining of mineral sands can be by both dry mining and wet (dredge) mining methods. In some countries, mineral sands products, principally titanium minerals, are also recovered from hard rock mining methods. Dry mining is suitable where deposits are shallow, contain hard bands of rock, or are in a series of unconnected ore bodies.

Zirconia, also known as zirconium dioxide (Zr0 2), is found in its most natural form in the mineral baddeleyite. But it can also be chemically derived from zircon. It is the most commercially important oxide formed by zircon. The methods used to obtain zirconia from zircon, although distinct from each other, have three common features:

Zirconium also occurs in about 30 other recognized mineral species including baddeleyite. This metal is commercially produced mostly by the reduction of the zirconium(IV) chloride with magnesium metal in the Kroll process. Commercial-quality zirconium for most uses still has a content of 1% to 3% hafnium.

Relatively inexpensive, this process produced zirconium in quantities large and pure enough for industrial use. Since Kroll's breakthrough, zirconium has become an important element in several industries: steel, iron, and nuclear power. It is used in the steel industry to remove nitrogen and sulfur from iron, thereby enhancing the metallurgical ...
