Cement manufacturing begins with quarrying operations in which limestone in mines is quarried and brought to crusher for crushing. Limestone quarries are opencast mines. Often limestone appears as an outcrop right on the surface. At other times it is under an overburden that can vary in depth but is generally less than 3 metres thick.

Most limestone is made into crushed stone that is used in road base, railroad ballast, foundation stone, drainfields, concrete aggregate, and other construction uses. It is fired in a kiln with crushed shale to make cement. Some varieties of limestone perform well in these uses because they are strong, dense rocks with few pore spaces.
