Abstract: Aiming at the problems of difficult flotation separation of fluorite ore,calcite and barite,the research progress of pH regulator,inhibitor and collector in fluorite ore flotation was introduced,and the type,performance and action mechanism of inhibitor and collector in flotation separation at room temperature were emphatically introduced.It was founded that the collector generally had the disadvantages of poor moderate temperature,dispersibility and acid and alkali resistance via researhing.It was proposed that the collector modification treatment and combination reagents were one of the effective ways to improve the flotation effect of fluorite ore,and low temperature resistant,high selectivity flotation reagents were the main direction of future research was indicated.

Key words: Fluorite, Flotation, Combination reagents
