Limestone comprises 95% of core raw material for cement production. No wonder then that the cement sector governs demand, supply and pricing of limestone (as well as coal) to some extent. According to some estimates, around 180250 kg of coal and about tonne of limestone is required to produce a tonne of cement.
Limestone is a source of lime (calcium oxide), which is used in steel manufacturing, mining, paper production, water treatment and purifiion, and plastic production. Lime also has major appliions in the manufacture of glass and in agriculture.
High calcium limestone is utilized in the production of construction materials such as roofing shingles and asphalt paving. It is also used as an additive to animal feeds, in the production of glass and soil enhancement; in the wet scrubbing process for flue gas desulfurization for utilities and other industries and for mine safety in coal mining operations.
· Limestone has been quarried in Stoney Middleton dale for centuries, a principle industry and employer during the last century. Thousands of tons of rock have been removed to produce vital minerals and metals and to simply provide stone for village had many quarries along The Dale, spreading from Darlton quarry (opposite Lovers Leap Garage).
