liquid test results are presented herein. The use of heavy liquid for bench scale simulation and results are also discussed. Bench Scale Simulation – Heavy Liquid Separation Although not economically feasible in large scale operations, bench scale heavy liquid separation (HLS) testing is an ideal preliminary step to pilot scale DMS testing.

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 …

Heavy Liquid Separation. This step is the most important in the mineral separtion lab procedure. Heavy mineral separation removes all the minerals that are more or less dense than quartz. Minerals such as rutile (TiO2) and zircon (ZrSiO4) and coal will disrupt later chemistry. Procedure. Materials: 250 ml separatory funnels. Ring stands
