    Mineralogical analysis. A successful separation of a valuable mineral from its ore can be determined by heavy liquid testing, in which a single sized fraction of a ground ore is suspended in a liquid of high specific gravity. Particles of less density than the liquid remain afloat, while denser particles sink.
