The annual production of limestone, estimated to be more than 6.6 Gt from deposits scattered all around the world, is about 9% of the world production of mineral raw materials (around 44 Gt yr −1), and is of the same order of magnitude as coal (7.3 Gt yr −1).
Mining Minister Focuses on Limestone
Jamaica's most abundant mineral is limestone, with a volume of approximately 50 to 60 billion tonnes. Limestone deposits in Jamaica account for 65 per cent of the island by weight, and 85 per cent of its surface coverage. A high proportion of Jamaica's limestone is considered"high purity grade."
Excavation of Limestone
Limestone is found near the surface (called a surficial deposit); hence, it is produced mainly from surface mines.By and large, limestone is mined by two methods: opencast stripping for hilly deposits and open-pit mining for plain deposits.

The Limestone Challenge
This type of deposit cannot be utilized for cement manufacturing process without blending with high grade limestone. About 97 per cent of Limestone is used in Cement Industry, 3 per cent in other industries like Iron and Steel and Chemical. Hence major consumer for limestone is cement industry.
