Variations in sample type, sample size and target minerals affect the approach to sample preparation. Minerals most frequently separated for isotopic analysis are zircon, monazite and potassium-rich rock forming minerals including K-feldspar and micas. Other minerals separated include titanite, rutile, apatite, xenotime,...

Mineral Separation Techniques

If the mineral is coarse grained, and is fairly abundant within the sample (modal content of > 10%), then a grapefruit sized sample is probably enough. On the other hand, if you are interested in separating an accessory mineral like sphene, zircon, or apatite, then your sample should be several kg in weight (minimum size...

Separation of apatite and zircon

The density difference between apatite and zircon allows hydrodynamic separation that can results in concentration around and sometimes even over 80%. From such concentrates it is possible producing crystal mounts for apatite FT or zircon U-Pb geochronology, in that the target mineral has proper density on the surface.

How are pyrite and zircon separated by using physical method?

The only problem is, if you have very rare and small grains of zircon in sediment. Then I would suggest to make heavy liquid - bromoform separation first and to apply hand-picking only on obtained small quantity of heavy fraction (separating zircon from pyrite and the rest heavy minerals). I don't know what kind of equipment...

The final step in mineral separation is by preferential flotation of mineral fractions by heavy liquid. Nonmagnetic fractions first undergo separation by sodium polytungstate (SPT; 2.85 g/cm3) and finally by methylene iodide (MEI; 3.3 g/cm3). At the end of separation, the final fraction should contain minerals such as zircon,...
