The relationship between mineralogy of fluorine ore with its floatability (Case study: Kamarposht fluorine mine)

Fluorine sample used in the study was supplied from Kamarposht (Savadkooh) Fluorine miner. First studies on KamarPosht fluorine particles is for concentrating and high grading and receive to metallurgical grade extent.a sample received from accumulation of blasting orebroken in mine with 100Kg weight that the 80 percent of materials are under 500 micron. On Fluorine samples also microscopic studies, freedom degree and flotation tests 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 of oleic acid is used on fluorine flotation tests. Also for reaching to concentration with proper grade, was been used from sodium silicate inorganic depressant as depression of silicate minerals and sodium carbonate for regulation of pulp PH and metal salt of aluminum sulfate for depression of calcite.Finally %35 grade fluorin of feed reached to % 61/4 grade and % 85/88 recover by using flotation tests, that is metallurgical grade extent and main scope of the studies.
