Olivine Powder and Olivine Sand (MgFe)₂SiO₄

Olivine is a magnesium iron silicate ((MgFe)₂SiO₄ with an olive green color and is one of the most common minerals found on earth. Olivine is hard, dense, and heavy. It has good insulating values due to low heat conductivity and high refractoriness. It is inert and has high chemical and mineralogical stability but weathers quickly. It is being looked at for its ability to sequester carbon dioxide in hopes it can aid in climate change mitigation.

MgO= 45% to 49%,
SiO₂= 39% to 42,
FeO= 6% to 8%,
CaO= 0.2% to 0.3%,
Cr= 0.1% to 0.4%,
Ni= 0.1% to 0.3%
Al₂O₃= 0.2% to 0.8%
Trace Elements= 0.3% to 0.5%
Typical Applications

Olivine is a gemstone in crystalline form. It also uses metallurgy as a slag conditioner and in the steel industry as a refractory. It also has been used to make refractory bricks, as casting sand, and as a lining in furnaces. It is a source of magnesium metal.
