It is one of the most frequent minerals on Earth, and has also been recognized in meteorites and on the Moon, Mars, and comet Wild 2. Rocks Found In Mineral. Ultramafic igneous rocks. Chemical Formula (Mg, Fe)2SiO4. Domestic production and use .
done by mining abundantly available and easily weatherable rocks, milling them and spreading the grains over the surface of the land or in shallow seas. Another way of applying this approach is to inject CO 2 into peridotite rocks that are rich in the easily weatherable olivine (Schuiling, 2006b, Kelemen & Matter, 2008). The heat
Olivine is the most abundant mineral in the upper mantle, making up over 50% of it. There large reserves all over the world found near the surface, in a formation called dunite, which consists of greater than 90% olivine. The current price is also attractive, at $25 a ton with the ability to go below $10 a ton with increased mining.
The amount of olivine necessary for these applications is extremely large – comparable to present day global coal mining, 10 which would bring serious and vast mining impacts. When energy inputs such as mining, processing and transportation are included, the overall energy requirement for enhanced weathering is huge. 11

The Eh was not measurably affected by oxidation over the range pH 3 to pH 11. As with chromite, low solubility of oxidizable species in olivine explains the insensitivity of solution potential to oxidation of the olivine. Comparison of Chromite and Olivine Flotation Behavior. The maximum flotation of both chromite and olivine occurs near pH 4.
Olivine gemstones have been used for thousands of years. It was believed that this stone brings power, influence, prosperity and happiness to its wearer.
