Limestone quarry, quarrying, cement raw materials

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.
