How Is Calcium Mined Or Produced

Data for the annual production of calcium carbonate are not readily available. Approximately 1 billion tonnes of its two principal ores limestone and dolomite are mined annually in the US. Given the relative amounts of lime that is used in different countries an estimate of worldwide mining of calcium carbonate is 15 billion tonnes a year.
