The Copper Mining Process. The laborious task of mining copper ore by hand made it difficult to obtain large quantities for production. During the Industrial Revolution, coal and steampowered machinery paved the way for a huge increase in copper production with mines smelting between 200 and 300 tons of copper ore per week.
In the calcium looping process, the two species are calcium carbonate (CaCO 3) and calcium oxide (CaO). The captured carbon dioxide can then be transported to a storage site, used in enhanced oil recovery or used as a chemical feedstock. Calcium oxide is often referred to as the sorbent.
