Limestone Wikipedia

Limestone is a common type of carbonate sedimentary rock.It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes have likely been more

What is the difference between lime and limestone?

Limestone is calcium carbonate mined from the ground and crushed for various end uses. When high calcium limestone is burned or calcined in a lime kiln, quicklime (calcium oxide) is produced. Quicklime can then be reacted with water to produce hydrated lime (calcium hydroxide).

Lime (material) Wikipedia

Lime is a calcium-containing inorganic mineral composed primarily of oxides, and hydroxide, usually calcium oxide and/ or calcium hydroxide.It is also the name for calcium oxide which occurs as a product of coal-seam fires and in altered limestone xenoliths in volcanic ejecta. The word lime originates with its earliest use as building mortar and has the sense of sticking or adhering.
