Zirconium is used to make the cladding for uranium oxide fuel elements. As mined, zirconium contains 13% 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.

Decreasing ore grades of existing or new iron ore deposits require predictive solutions to efficiently sort and blend iron ore for optimal and profitable beneficiation and downstream processing. Elemental and mineralogical composition as well as predictive models for the upgradability, based on metallurgical parameters, such as washable constituents, play an important role for iron ore producers.
Zirconium and hafnium are corrosionresistant metals that are widely used in the chemical and nuclear industries. Most zirconium is consumed in the form of the main ore mineral zircon (ZrSiO4, or as zirconium oxide or other zirconium chemicals. Zirconium and hafnium are both refractory lithophile elements that have nearly identical charge, ionic radii, and ionic potentials.
Zirconium (/ z ər ˈ k o ʊ n i əm / zərKOHniəm) is a chemical element with the symbol Zr and atomic number 40. Its atomic mass is It is a lustrous, greywhite, strong transition metal that resembles is used as an alloying agent for its strong resistance to corrosion.

Thus, the speciation and the structure of various zirconium species in ammonium zirconium carbonate solutions were investigated over a wide range of total carbonate and ammonium concentrations. By employing extended Xray absorption fine structure analysis, and Raman and 13 C NMR spectroscopy, it was found that four carbonate ions coordinate bidentately to the zirconium ion.
» Aluminum Zirconium Pentachlorohydrate Solution is a polymeric, loosely hydrated complex of basic aluminum zirconium chloride that encompasses a range of aluminumtozirconium atomic ratios between :1 and :1 and a range of (aluminum plus zirconium)tochloride atomic ratios between :1 and :1.

· 1 Wash, filter and grind the granite ore with into smaller pieces. 2 Put the ground ore into a tank containing a dilute cyanide solution and add zinc. The chemical reaction between a dilute cyanide solution and zinc will separate the gold from the ore. 3 Use a filter press to remove the gold from the solution.
Zirconium is used for steel alloys and colored glazes. It is not effected by the bombardment of neutrons, so it is used as an inner lining in nuclear reactors. Zirconium compounds are used for bricks, ceramics and abrasives, flashbulbs, explosive primers, lamp filaments and artificial gemstones.
Zirconium is an element of considerable petrogenetic significance but is rarely found in hematite at concentrations higher than a few partspermillion (ppm). Coarsegrained hematite ore from the metamorphosed Peculiar Knob iron deposit, South Australia, contains anomalous concentrations of Zr and has been investigated using microanalytical techniques that can bridge the micron to nanoscales ...
