Abstract :

Fluorine sample used in the study was supplied from Kamarposht (Savadkooh) Fluorine miner. First studies onKamarPosht fluorine particles is for concentrating and high grading and receive to metallurgical grade extent.asample received from accumulation of blasting orebroken in mine with 100Kg weight that the 80 percent ofmaterials are under 500 micron. On Fluorine samples also microscopic studies, freedom degree and flotationtests have been done. Results of petrograghy is shown associate minerals with fluorine include quartz, calcite,barite and dolmite which can cause some problems in fluorine processing. Because of this anionic collector ofoleic acid is used on fluorine flotation tests. Also for reaching to concentration with proper grade, was been usedfrom sodium silicate inorganic depressant as depression of silicate minerals and sodium carbonate for regulationof pulp PH and metal salt of aluminum sulfate for depression of calcite.Finally %35 grade fluorin of feedreached to % 61/4 grade and % 85/88 recover by using flotation tests, that is metallurgical grade extent and mainscope of the studies.
