Ans: Olivine is used across many places around the world. It is used for cheap processes that can help produce sequester CO2 by implementing various mineral reactions. It is known as enhanced weathering. Removing elements by reactions in Olivine is the best option for all the industrial workers. As Olivine is available in huge quantities, it reacts quickly with any acid (CO2) that is available in the atmosphere itself. When you crush Olivine, it weathers entirely within a couple of years. Although it depends on the sizes of the grains; however, the process is quite faster. All the carbon dioxide is produced by igniting a liter of oil that is sequestered by a small quantity of Olivine.The end-products of these reactions are Silicon Dioxide, small quantities of iron oxide, as well as magnesium carbonate. It is also utilized as an alternative for dolomite in many steelworks. Also, it is widely used in the aluminium foundry industries.
