Two general phases of limestone production exist: quarrying and processing.
2 Limestone Quarrying and Processing Operations 2.1 Limestone Limestone is a sedimentary rock composed primarily of calcium carbonate with the occasional presence of magnesium. Most limestone is biochemical in origin meaning the calcium carbonate in the stone originated from shelled oceanic creatures. Limestone can also be chemical in origin
Mining and Quarrying. The process begins with limestone extraction from a quarry or mine. This may involve drilling, blasting, and other methods to break the limestone into manageable sizes for further processing. Primary Crushing. The extracted limestone is transported to the primary crusher, usually a jaw crusher. This crusher reduces the ...
