Zirconium is chiefly obtained from zirconium dioxide (baddeleyite) and zircon. These relatively heavy minerals are found in placer deposits and wind-worked sands, and are mined in Australia, South Africa, the USA, Russia and Brazil.
Zirconium is a silvery-white metal primarily produced from the mineral zircon, although a very small number of deposits are mined for the zirconium oxide baddeleyite instead. Zircon can occur as a by-product of the mining and processing of the titanium minerals ilmenite and rutile, as well as a byproduct of tin mining.
Australia now has the biggest share of zirconium reserves as a single country. Zirconium mine production; In 2013, global zirconium production totaled 1.44 million tonnes，registering a 1.4% year-on-year drop. Nearly half of the world’s zirconium (42%) was produced in Australia, followed by 25% in South Africa and 10% in China.
About Zircon. Zircon, also referred to as zirconium silicate (ZrSiO 4), is a co-product from the mining and processing of ancient heavy mineral sand deposits.Mined mainly in Australia, it can be used either in its coarse sand form or milled to a fine powder. Its properties ensure that it is used in many everyday products, including ceramic tiles and medical implants, as well as having major
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.

Zirconium is used to make the cladding for uranium oxide fuel elements. As mined, zirconium contains 1-3% per cent of hafnium, which is chemically very similar, and although it is difficult to separate the two elements this has to be done for the metal used in the nuclear industry because hafnium absorbs neutrons very strongly.
