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. ...
Sublimation kinetics of zirconium tetrafluoride

Pretorius, C.J.; Pienaar, A.D.; Crouse, Philippus L.; Niemand, H.F. (Trans Tech, 2014)

An important step of a new process being developed for the beneficiation of the mineral zircon (Zr(Hf)SiO4) to produce nuclear grade zirconium (Zr) metal, is the separation of the Zr from the hafnium (Hf). Zr ores typically ...
