how to remove impurities from zircon sand

Highpurity zircon (ZrSiO 4) nanopowder was successfully produced from Indonesian natural zircon sand using a lowcost purification approach via magnetic separation, immersion in HCl, and reaction with NaOH, followed by a topdown nanosizing process using wet ballmilling for 10 h and annealing at 200 °C for 2 h.Furthermore, polymorph zirconia (ZrO 2 – amorphous, tetragonal, and monoclinic

Recovery of scandium, yttrium and lanthanides .

This is a process for extracting scandium from zircon ore. It utilizes feeding zircon sand to a fluidized bed chlorinator at 800°° C. to produce a vaporous (principally zirconium and silicon chlorides) phase and a solid residue and recovering scandium from the solid residue. The very low level of scandium present in zircon ore is concentrated in the residue, making recovery of scandium
