Efficiency of heavy liquid separation to concentrate magnetic particles
In this study, we explored heavy liquid separation on marine dry bulk sediments comprising complex magnetic mineralogies (Franke 2006; Franke et al. 2007b.) as an alternative extraction method to achieve a more complete 'magnetic' fraction, consisting of the heavy mineral portion (density >3.0 × 10 3 kg m −3). This fraction …

Three different types of heavy liquids and a magnetic separator (Frantz) can be found in the mineral separation room. This room is mostly used for separating heavy minerals - like zircon, monazite and apatite - from lighter minerals. Zircon and monazite are important minerals for U/Pb dating with the help of laser ablation and a mass spectrometer.
