Calcium is what is known as an essential element, meaning that it is an element which is absolutely necessary for life processes. Which is what the old milk TV adverts were trying to tell us after all. Calcium is used to produce the minerals contained in bones, shells and teeth through a process called biomineralisation.

Calcium carbonate - Essential Chemical Industry

The heated air from the coolers is returned to the kilns, a process that saves fuel and increases burning efficiency. The resulting solid comes out of the kiln as grey balls, about the size of marbles and is known as clinker. The clinker is ground to a fine powder and mixed with calcium sulfate (gypsum) to make the familiar grey fine powder.
