Also, limestone filtration can increase the calcium content in water, which scientists say has a beneficial health effect on those who drink such water. The limestone water filter works through a process known as "absorption" Limestone is a powerful filtering method since it filters water using a process known as "absorption".
Uses of limestone. Limestone is mined in vast amounts. An estimate in The Essential Chemical Industry suggests it could be 15 billion tonnes a year worldwide. It is used in the construction industry: as a building material; to make cement, which in turn is used to make mortar and (in huge quantities) concrete; in road building.

Cement and concrete are not the same. Cement is an ingredient—a mixture of powdered limestone and clay—added to water, sand, and gravel to make concrete. Concrete was made possible by the development of cement, and to trace the history of cement, we must trace the use of its components.
Northern Oman hosts some of the world's best exposures of pillow lavas: dark, bulbous, pillow-shaped rocks that form where incandescent lava instantly chills as it oozes directly into the frigid sea. The sultanate's pillow lavas formed 95 million years ago, and the same process is occurring today off the coast of Hawaii. Because the pillows ...

Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don't dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3- ions, which are very soluble in water, and the limestone will dissolve. Or, if there is …
