Our Source of Inspiration: OLİVİN

Oliving mining is a rather new procces when compared to the other minerals. Olivine mining function in very critical positions for both it’s chemical and physical properties in Iron&Steel, Casting, Sand Blasting in the developed and developing contries in the world for 20-25 years.

Olivine consumption has incread to a large extent as both for the prohibition of free silica content materials’ in developed contries for environment, healt concerns and for being more economical when compared to the alternative products intended to be used instead of olivine. (In Turkey, the usage of the products and raw material containing free silica has been prohibited in 2009 by the Ministry of Health.)

Olivine doesn’t contain any free silica in it’s content.

Olivine as a terms stands for the medium silcate grup containing the mixture of Forsterite (Mg2SiO4) and Fayalite (Fe2SiO4) and economically usable olivine products generally containes %95 Fosterite.

Olivine is known for it’s colours green/dark green and the hardness which is around 6.5-7 in mohs scale. The density is variable in accordance with the Fe content of the product between 3.22-4.49 gr/cm3. Olivine is find in ultra basic rocks. Olivine mineral is one of the first minerals that is cyristalized in magma. In ultrabasic rocks are mostly composed of dünite olivine. Percentage of olivine in dunites is around %95-99. Industrily usable olivine contatains chemical levels of MgO %46 min., SiO2 %38-42 max and Fe % 7-8 min. Also the total percentage of the other metal oxides needs to be under %3 and the loss on ignition value %2 max.
