Quarrying metho, dwhich is the widely accepted and practiced method especially on limestone deposit for cement manufacture, will be used to extract the material. There will be clearing, drilling, blasting, loading, hauling, be nching, and road and dump maintenance. Mining will be s imultaneous with processing. Crushing
The limestone is used as a source of lime (lime is created by burning/heating limestone rock in kilns, thereby driving off the CO 2) and is crushed for road metal, concrete, and cement. It is used in the manufacture of calcium carbide and other chemicals, in paper, sugar, and open hearth steel manufacture, and as a flux in iron and steel blast
Limestone is now mined using surface and underground methods. Surface quarrying is the most common method of producing limestone in Missouri. Also, it is typically the most economical method. Many surface operations are simply hillside cuts or open pit quarries. Controlled blasting at the quarry face is used to break the rock into pieces.
