Olivine is the primary mineral component in mantle rock (called peridotite) and ocean floor rock (called basalt). It is characteristically green when not weathered. The chemical formula is (Fe, Mg)2SiO4 ( Fe, Mg) 2 SiO 4. The comma between iron (Fe) and magnesium (Mg) indicates these two elements occur in a solid solution.

The size reduction of olivine into 40, 100, and 250 μm was generated utilizing grinder and sieve machines in order to investigate the effect of increasing surface area on carbonation rate. As conclusion, by increasing the temperature of reaction and reducing size of olivine, the carbonation rate of olivine mineral was increased.
