In order to improve the separation of valuable minerals from serpentine or other similar gangue minerals it is logical to expect that the application of dispersants such as sodium grain size of the serpentine and its intimate association with fine grained spinels or hydrated oxides such as goethite or lepidocrocite which makes physical separation of the minerals almost impossible It is also suspected that in some cases the amount of magnesia reported is in correct and is really due to the mineral impurity brucite

Serpentinites are rocks consisting of serpentine group minerals eg antigorite chrysotile and lizardite produced by the hydrothermal alteration of Mg‐rich olivine and orthopyroxene in ultramafic rocks at relatively low temperature Evans et al Guillot and Hattori Serpentinites can constitute up to 25 by volume of the upper part of the oceanic lithosphere Cannat et alThe effect of sodium hexametaphosphate SHMP on the separation of serpentine from pyrite and its mechanism were studied systematically through flotation tests sedimentation tests surface
