Determination of low content silicon dioxide in fluorite by inductively coupled plasma atomic emission spectrometry;

Study of New Flotation Technology of Fluorite Under Normal Temperature;

Research & development of national standard specimen of fluorite;

Analysis on CaF_2 in Fluorspar;

A method for the determination of CaF2 in fluorspar samples by X-ray fluorescence spectrometry with sodium metaphosphate as flux is proposed.

Aiming to the geological characters of fluorite deposits in Shuangjiangkou of Hunan,integrating the geological backgrounds,the geological conditions,the cause of formation of deposits and the factors of controlling ores in this district,the prospecting marks offluorite deposits have been suggested and the prospecting foreground is good.
