More information

The mineral olivine (Peridote) is a nesosilicaat with the chemical formula (Mg, Fe) 2SiO4, wherein the end members between the magnesium and iron are formed by the minerals set of forsterite (Mg-rich), and fayalite (rich in Fe). Olivine has an orthorhombic crystal system and it crystallizes in a somewhat flattened shape, but can also occur in solid or granular form. It breaks up conchoidal fashion and is somewhat fragile. The hardness of olivine is between 6.5 and 7. The average density is 3.32 kg / l and the mineral has a glass luster. Usually it has an olive green in color (hence the name), but it may also be reddish by the oxidation of trivalent iron. It is transparent to translucent. Olivine occurs as a rock-forming mineral in mafic igneous rocks and in some metamorphic rocks. It has also been discovered in meteorites and Mars traced by the US spacecraft Mars Odyssey. The Mars Exploration Rovers have also confirmed attendance. Olivine is formed in magma which is rich in magnesium and low in silicates (silicon dioxide). It is an important mineral in rocks and gabbro, Norite, the mantle rock peridotite (dunites) and as small crystals in basalt. The metamorphosis of impure dolomite or other sedimentary rocks with lots of little magnesium and silicate also appears to form olivine. Olivine is a widely used tool for façade cleaning. Small olivijnkorrels be blasted with water on the wall so that the contaminated layer is removed. Peridot is better suited for this than regular grains of sand, through its greater hardness. Because at this time intensively searched everywhere in the world is made to low-cost processes to bind CO2 is olivine mineral in the interest come to be. Peridot is a basic rock. It reacts relatively quickly with the (acid) CO2 in the atmosphere. Crushed olivine weathers a result, depending on the grain size, in a few years a whole. To CO2 which 1 liter of oil when burned produces binding (neutralizing) is slightly less than 1 liter of olivine needed. The reaction is exothermic. The end products of the reaction are, depending on the composition of the olivine, magnesium carbonate, or silicon oxide (sand)
