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.
Sustainable Utilisation of Quarry By-products. The seeker operates one of the largest limestone quarries in the world: approximately 6 million tons of limestone aggregates are produced each year. The use of a wet processing technology for aggregate production generates as a by-product about 300 000 t/year of quarry fines (0/100 µm, D50 = 12 µm).
