In fact, extracting pure calcium via electrolysis, the developed process is clean and reduces unwanted wastage. However, in terms of mining its ore, there are a few issues, environmentally in particular. In terms of quarrying limestone (an ore of a calcium), the waste product and results of pollution need to be taken into account.

Calcium carbonate (limestone) is heated to form calcium oxide (quicklime) and carbon dioxide It is an endothermic reaction and the equilibrium lies far to the left at low temperatures. Only at about 1200 K does the partial pressure of carbon dioxide exceed atmospheric pressure and the decomposition proceeds to completion.

An ore is usually a compound of the metal mixed with impurities. When the metal is dug up, a method must be used to separate the metal from the rest of the ore. This is called extracting the metal. The method of extraction depends on how reactive the metal is. The more reactive the metal, the more difficult it is to extract from its compound.

Surface mining is used to obtain mineral ores that are close to Earth's surface. The soil and rocks over the ore are removed by blasting. Typically, the remaining ore is drilled or blasted so that large machines can fill trucks with the broken rocks. The trucks take the rocks to factories where the ore will be separated from the rest of the rock.
