Zirconium and hafnium are contained in zircon at a ratio of about 50 to 1. Zircon is a coproduct or byproduct of the mining and processing of heavy-mineral sands for the titanium minerals, ilmenite and rutile, or tin minerals. The major end uses of zircon are refractories, foundry sands (including investment casting), and ceramic opacification.

· Zirconium and hafnium have close atomic radii (1.45 Å and 1.44 Å, respectively), and similar valence electron configurations of 4d 2 5s 2 and 5d 2 6s 2, respectively . Therefore, Zr–Hf separation has been a topic of investigation for several decades.
· We are very pleased to engage our processing consultants, SGS Canada, to provide the preliminary metallurgical work on zirconium and hafnium recovery from the SILVER FOX and FOXTROT material.
In this case, a chemical engineer who had been at a zirconium and hafnium processing plant for seven years was found to have granulomatous lung disease. As no similar damage was found on all other employees, it was concluded that the situation was most likely due to relatively high levels of beryllium prior to zirconium contact.
