Limestone is a naturally occurring and abundant sedimentary rock with high levels of calcium, carbonate, and dolomite along with small amounts of other minerals. It is extracted from quarries and underground mines all over the world. The word “lime” refers to products derived from calcined limestone, such as quicklime and hydrated lime.
Much has been written about lime and its importance in commerce both in the past and in today’s market economy. Its use predates recorded history and most ancient languages have a word for calcium oxide. In Latin it is calx, from which the name of the element calcium is taken. In Old English, its name is lïm, which is the origin of the modern commercial name for calcium oxide, namely lime.
Lime and limestone products are among the oldest materials used by humans for a very diverse range of applications. Today these products serve as an essential building block in every industrial process, as well as in common household products or uses like plaster, toothpaste, glass, sugar, water treatment and paper.
