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, apatite, monazite ...

Rocktype | Sample preparation

We can make heavy mineral separates from sand or solid rock. Rocks are dis-aggregated to sand in a jaw crusher. Sand is sieved to the appropriate size fraction. Mixed sand is separated into light and heavy fractions using LST fastfloat heavy liquid with a density of 2.89 g/cc. The HM separates are cleaned and dried, ready for embedding in resin.
