the use of lithium heteropolytungstate in mineral separation

The use of lithium heteropolytungstate in the heavy liquid ...

Here we examine the use of a synthetic heavy liquid, lithium heteropolytungstate solution (LST), to extract pollen from the sediments of a desert paleolake, Manix Lake, California, USA. Palynologists have used heavy liquid separation as an alternative to chemical separation of pollen from mineral matter for over 60 years (Brown 2008). A

Mar 24, 2021  This way an easy separation of the minerals can be achieved. LST and SPT are cleaned and recycled after their use. DIM (diiodomehtane) has a very high density (3.325g mL-1) and helps to separate the heavy minerals which were part of the heavy fraction during LST or SPT treatment. In our case, DIM helps to separate apatite from zircons.
