Copper / nickel / lead and zinc mining

Cut stone and stone product manufacturing

Ground or treated mineral and earth manufacturing

The activity generating the emissions is limestone production, crushed, washed. The Reference Product is limestone, crushed, washed. The product "limestone, crushed, washed" represents 1 kg of washed crushed limestone. Limestone is a naturally occurring mineral that consists principally of calcium carbonate (CaCO3). It is found in many forms and is classified in terms of its origin, chemical composition, structure, and geological formation. This product is modelled as 97% calcite (CaCO3), 2% silica (SiO2) and 1% magnesite (MgCO3). Limestone occurs widely throughout the world and is an essential raw material for many industries. Limestone is generally used for construction, cement, quicklime, agriculture, metal refining and flue gas desulphurisation: Construction: Limestone is the most widely used crushed rock, although it is generally sold in form of sand and gravel. Cement: The production of cement is the main use for chalk, and a major use for dense, high-calcium limestone. Quicklime: Approximately 1.8 t of limestone is required per 1.0 t of quicklime. Agriculture: Many crops grow best under neutral to slightly acid conditions (i.e., pH between 6 and 7). Thus soils which are more acidic than pH 6 generally benefit from the application of limestone. Metal refining: When limestone is used in metal refining it is initially converted to quicklime, which reacts with acidic oxides (e.g., SiO2, Al2O, and Fe2O3) to produce molten slag. Flue gas desulphurisation: A growing use of limestone is in the treatment of flue gas from combustion processes to remove sulphur dioxide. The Reference Product amount is 1. The cut-off classification is allocatable product. The activity type is ordinary transforming activity. Please refer to the ecoinvent documentation for full details: https://ecoquery.ecoinvent.org/3.12/cutoff/dataset/8729/documentation
