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.

olivine flotation equipment

Olivine flotation (Ni/Co) Flotation of olivine in the mid-mantle during an early magma ocean would perhaps satisfy the superchondritic Mg/Si ratio (Agee and Walker, 1988). However, McFarlane and Drake (1990) have shown that the Ni/Co ratio of such a layer would be 25% higher than that in the observed upper mantle.
