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.

The iron in the calcium carbonate is extracted by treating an aqueous calcium carbonate slurry with an iron chelating agent while heating and agitating the slurry and introducing a carbon dioxide containing gas to control the pH during the extraction process. The extracted iron is then separated from the calcium carbonate by filtration.

Role of limestone (calcium carbonate) in the extraction of iron. Limestone removes impurities present in the iron ore. This is achieved because, at high temperatures, calcium carbonate will undergo thermal decomposition to calcium oxide. The calcium oxide then reacts with the acidic impurities (mainly silica) present in the iron ore to form ...

The limestone is added to convert this into slag which melts and runs to the bottom. The heat of the furnace decomposes the limestone to give calcium oxide. This is an endothermic reaction, absorbing heat from the furnace. It is therefore important not to add too much limestone because it would otherwise cool the furnace.
