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.
Fig. 8 presents the overall contribution of milling in the zircon production process. The milling process is much more relevant for zircon production than it is for alumina. This is due to the energy consumption associated with electricity use in the mill, as well as thermal energy for the drying process applied during wet milling.
