Solvent extraction systems for the separation of zirconium (IV) and hafnium (IV) from different
aqueous media, such as sulfate, chloride and nitrate were reviewed. The important …

Large amount of hazardous waste generated by the uranium purification process poses a
potential threat to the environment. However, it also contains valuable metals like uranium …

Abstract High-purity zircon (ZrSiO 4) nanopowder was successfully produced from
Indonesian natural zircon sand using a low-cost purification approach via magnetic …

Spectrophotometry was used to determine trace amounts of Zirconium (IV), Mercury (II) and
Uranium (VI) in environmental, biological, pharmaceutical and industrial samples. The …

Solid pollution has been an issue in mineral processing for decade. One of these pollutants
is zircon sand mining waste (zircon tailing). Due to the concentration of rare earth minerals …

H2SO4 was ensured to be the best candidate for Zr leaching from the eudialyte. The
resulting sulfuric leach solution consisted of Zr (IV), Nb (V), Hf (IV), Al (III), and Fe (III). It was …

A method to prepare amorphous silica particles from zircon has been developed using the
fluorination method through a three-step process: the fluorination of zircon using ammonium …

In this work, the thermal and microstructural analysis of the reaction pathways of natural
zircon with ammonium bifluoride (NH 4 HF 2) under N 2 gas were investigated from room …

This work describes the processing of a Brazilian zircon (ZrSiO4) concentrate via fusion with
sodium hydroxide. The goal was to produce a zirconyl sulphate solution (ZrOSO4). The …

We studied yttrium extraction from untreated zircon sand processing waste tailings.
Xenotime mineral as the rare earth element source with an abundance of yttrium (REY) was …
