This concentrate is then acid washed to remove impurities, (for example, oxides or hydroxides (Gerson, 2006), and thus increasing the difference in the resistivities between the rutile and the zircon. After drying, this zircon-rich stream is again subjected to an electrostatic separation stage to remove as much of the rutile as possible; during this last separation step it is found that there ...

Zircon - an overview | ScienceDirect Topics

Zircon (ZrSiO 4) is an important mineral found in the igneous rocks and sediments of the earth's crust [182], and it transforms from the zircon (S.G. I4 1 /amd, Z = 4) to the reidite (scheelite I4 1 /a, Z = 4) form at ∼23 GPa. This transformation was suggested to be brought about by shear deformations followed by small displacement of the atoms and rotation of the SiO 4 tetrahedra [18].
