Olivine Mineral | Physical - Optical Properties, Uses ...

Olivine Uses. Olivine is a mineral that isn't regularly utilized in enterprise. Most olivine is used in metallurgical strategies as a slag conditioner. High-magnesium olivine (forsterite) is introduced to blast furnaces to take away impurities from metallic and to shape a slag. Olivine has also been used as a refractory material.
