| Abstract: | A simple and accurate methed for the determination of hafnium in Zircon concentrate and zircite has been developed. The lower determination limit for hafnium is 0. 01 %. The relative standard deviation is 1. 5%, and the additive recovery lies between 95% -102% at the hafnium dioxide content 1.90% in zirconite;while at the hafnium dioxide content 0. 034% in zircite, they are 4.0% and 0. 97%-102% respectively. |
