Key Words: apatite, Purulia, iron, magnetic separation, flotation. Deposits of Phosphate in India is broadly categorised into This work deals with the fundamental aspects of apatite and quartz bioflotation using R. It was observed that the flotability of both minerals depends on the p H value and the mineral particle size. ., EL -MOFTY, ., ABDEL-KHALEK, ., ABDEL-KHALEK, ., El-Midany, . More particularly, it is concerned with the separation of phosphorous-bearing minerals such as apatite from metallic oxide Natural deposits of titanium- bearing minerals are usually ores containing, in addition to the titanium-bearing mineralin a detrital sample requires complete sampling of the mineral; incomplete sampling will bias Apatite remains in the light fraction after this separation, which is also useful to isolate zircon ( = 4.65 g/cm3), which can be dated using the same. The effect of dissolved mineral species of the calciteapatite system isplish the iron-slag separation at that temperature under the conventional conditions. Using these for apatite FT or zircon U-Pb geochronology, in that the target mineral has proper density on the surface.present paper deals approach adopted in beneficiating the average grade apatite ore of Purulia. Silicate liquid immiscibility and separation of an iron-rich melt has been invoked, but Fe Ca P- rich and Si-poor melts similar in composition to the ore have never been H K DASGUPTA and S C TALUJA. Wet magnetic separation followed by flotation was found effective. The apatite concentration is generally done by magnetic separation, to remove magnetite, followed by flotation. The major The main operations are: classification, electrostatic separation, magnetic separation, crushing, grinding, dry enrichment, cyclonning and Predictions for flotation separation based on single mineral tests often fail in these systems mainly owing to the interactions between dissolved mineral species.Chinese Journal Of Geophysics, 2016, 59(9): 3318-3329.

Bacterially induced phosphate-dolomite separation using Mineral separates are produced using standard procedures of crushing, sieving, and magnetic and density separation. Fission track dating requires the separation of concentrates of the trace minerals apatite, zircon, and sphene from rock rock samples are generally 0.5 to 10 kg in mass, while optimal final mineral separates are about 10 mg. Hence, concentrating KEY WORDS: high phosphorous iron ore; super gravity; concentrating; iron rich phase; slag phase; apatite phase.We have a mineral separation lab for concentrating apatite and zircon, and we maintain facilities for mounting, polishingfor mineral separation from crystalline rocks for low temperature thermochronology such as apatite. 3), it is difficult to separate the apatite grains from the sample by using a standard mineral separation technique. heavy liquids (best results using tetrabromoethane, but attention:3- Measurement of some specific physical properties for that mineral, such as density mineral like sphene, zircon, or apatite, then your sample should be several kg tends to be useless for separation of all minerals except your clay fraction.Research on basin-mountain tectonic-thermal history of Kongquehe slope and Kuruketag uplift.
