Production

The whole process of making any type of lime all begins at the limestone quarry after careful surveys. Most limestone is extracted through blasting. Behind the rock face, holes are drilled to place the explosives. When detonated, the explosion dislodges each time up to 30,000 tonnes of stone.

Soil Acidity and : Basic Information for Farmers and …

Lime pellets are not large grains of solid limestone; they are formed from lime that has been finely ground. Pellets are less dusty and easier to spread, but they are more expensive than powdered lime. Pelleted lime comes into contact with fewer soil particles than finely ground lime. As a result, soil pH changes are slower with the pellets.

Utah's Limestone

Limestone's major industrial uses are as crushed stone, in lime manufacture, and in cement manufacture. Crushed stone is used for a variety of construction purposes like road base and concrete aggregate. In 2003, companies in the United States produced 1.08 billion tons of crushed limestone with a value of $5.46 billion.

Limestone extraction – underground mining …
