Dunite (Olivine Sand)

Dunite is an igneous, plutonic rock, of ultramafic composition, with coarse-grained or phaneritic texture. The mineral assemblage is greater than 90% olivine, with minor amounts of other minerals such as pyroxene, chromite and pyrope. Dunite is the olivine-rich end-member of the peridotite group of mantle-derived rocks. Varied Applications In Refractory Industries to manufacture Dunite Refractory Bricks. As flux material in Steel Plants replacing limestone. In forging industries abroad in powder form to replace silica sand.
