Kinetics and thermodynamic parameters for the manufacturing of anhydrous zirconium tetrafluoride with ammonium acid fluoride as fluorinating agent

Pretorius, C.J.; Du Plessis, W.; Nel, Johannes T.; Crouse, Philippus L. (Southern African Institute of Mining and Metallurgy, 2012-07)

More than 30 percent of the global demand for zircon (ZrSiO4) is supplied by South Africa. A significant amount of the zircon is exported, and beneficiated products are then imported for industrial applications locally. ...
Microwave digestion of zircon with ammonium acid fluoride: derivation of kinetic parameters from non-isothermal reaction data

Nhlabathi, T.N.; Nel, J.T.; Puts, Gerard Jacob; Crouse, Philippus L. (Elsevier, 2012-11-21)

Zircon is notoriously inert. Aggressive processing methods such as alkaline fusion are conventionally used to extract zirconium values from the mineral. In this study results are presented with respect to microwave ...
