Description
Limestone is used in the construction industry as raw material for aggregates and lime, in the metallurgical industry as a flux, and also for the production of cement and glass; this dataset includes major raw materials, auxiliary materials, energy inputs, atmospheric emissions, and waste generated during the production process, but infrastructure such as manufacturing of production equipment and construction of facilities are excluded from the system boundaries of the dataset; this dataset was compiled from data derived from multiple sources; the limestone mining process includes overburden removal, blasting, loading, crushing, and other operations until raw limestone ore is obtained.
Activity Description
The limestone mining process includes steps such as overburden removal, blasting, loading, crushing, and others, until the raw limestone ore is obtained.
Process Description
Limestone is a common carbonate rock composed primarily of calcium carbonate, widely used in construction materials, industrial raw materials, and the chemical industry. In the construction industry, limestone is used as aggregate and as a raw material for lime production; in the metallurgical industry, it serves as a flux; and it is also used in the manufacture of cement and glass.

Mining techniques include two methods: underground mining and open-pit mining. Underground mining involves extracting ore bodies beneath the surface, typically by excavating horizontal tunnels and shafts, followed by ore extraction and transportation underground. Open-pit mining refers to the extraction of ore bodies at the surface and is generally used for shallow deposits. This method includes processes such as blasting, digging, and loading.
