The chemical reactions used to refine minerals also contribute to climate change. For example, one of the first steps in making steel is to heat a mixture of iron ore, limestone and coke, a coal product, to extremely high temperatures. This purifies iron by removing oxygen, but it also creates CO 2 and carbon monoxide as a byproduct. …
