    Olivine Separation Normally, olivine separation is not done. However, olivine can be rapidly separated from rocks such as basalt using a variant on the froth flotation method known as grease tabling.Fayalite: Fe2SiO4. The intermediary variety, Olivine, is not scientifically recognized as a separate mineral, but is nevertheless well-established. The mineral Tephroite (Mn2SiO4), which many consider a member of the Olivine group, forms a series with Forsterite.Olivine: The mineral Olivine, peridot information and picturesreflecting stricter demands on quality. As a consequence, mineral separation could to a greater extent become part of the production process. Commercially, the term olivine could represent a range of different rock types including dunites, peridotites, serpentinites and Dry magnetic separation of olivine sand Rolf Arne KLEIV ...

  • Olivine mineral Britannica

    Olivines are an important rock-forming mineral group. Magnesium-rich olivines are abundant in low-silica mafic and ultramafic igneous rocks and are believed to be the most abundant constituent of the Earth’s upper mantle. Olivine also occurs in high-temperature metamorphic rocks, lunar basalts, and some meteorites.4 olivine in isolation (Fo89) and for a model (pyrolite) mantle composition. Mineral proportions are as volume fraction, shown by bold white lines; compositions are in terms of Mg/[Mg+Fe], and are shown by colours and by dotted contours at 1% intervals.

    The olivine minerals are important rock-forming minerals in mafic igneous rocks such as basalt and gabbro, and many peridotite rocks are almost entirely composed of olivine.
