The quarrying operation produces a large amount of solid waste at a rate of 88.18–132 tons/day (Hayyat, 2008). Solid waste from limestone quarrying has a variety of uses, ranging from the manufacturing of masonry blocks to cement production (Felekoglu, 2007; Turgut, 2008). In Pakistan, limestone is cheap and its transport expensive; …

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.
