Lime and Limestone Operations
The Company extracts limestone from its open-pit and underground quarries and then processes it for sale as pulverized limestone, quicklime, hydrated lime and lime slurry. Pulverized limestone (PLS) is a dried product ground to granular and finer sizes. Quicklime (calcium oxide) is produced by heating limestone to high temperatures in kilns in a process called calcination. Hydrated lime (calcium hydroxide) is produced by reacting quicklime with water in a controlled process. Lime slurry (milk of lime) is a suspended solution of calcium hydroxide produced by mixing quicklime with water in a lime slaker. PLS is used in the production of construction materials such as roof shingles and asphalt paving, as an additive to agriculture feeds, in the production of glass, as a soil enhancement, in the flue gas desulphurization process for utilities and other industries requiring scrubbing of emissions for environmental purposes and for mine safety dust in coal mining operations. During the year ended December 31, 2011 (during 2011), it sold almost all of its lime and limestone products in the states of Arkansas, Colorado, Illinois, Kansas, Kentucky, Louisiana, Maryland, Mississippi, Missouri, New Mexico, Oklahoma, Pennsylvania, Tennessee, and Texas.
