Mining Significance
Calcium is not mined as elemental metal; it is produced from abundant calcium-bearing minerals and rocks such as limestone, dolomite, gypsum, and fluorite depending on the end product. Limestone and lime are major bulk mineral commodities used in construction, environmental treatment, and metallurgical fluxes. For mining and mineral processing, calcium-bearing materials are also important reagents for pH control, neutralization, and slag formation.
