Limestone Simple English Wikipedia, the free encyclopedia

Limestone is a sedimentary rock, made up mostly of the mineral calcite, a form of calcium carbonate, CaCO3. The calcium carbonate is originally produced by living organisms. Later, some of it goes into solution in sea water. Limestone rocks include mainly organic remains and precipitated carbonate. Limestone makes up about 10% of the total volume of all sedimentary rocks.

Calcite, Limestone and Marble University of Waterloo

Limestone. A white 'lime' mud is deposited on the bottom of the sea. This white mud slowly hardens into a light coloured limestone that remains soft. When spring water evaporates on land, calcium carbonate forms a crust over moss, dead leaves, and the ground. It builds up a mound or terrace called tufa.

Limestone in industry Resources, conflicts and

Limestone is poured into blast furnaces when iron is being extracted from iron ore. In the blast furnace, the limestone acts as a 'flux', which changes into calcium oxide and carbon dioxide. The calcium oxide reacts with the silicon dioxide in sand to form calcium silicate (CaSiO 3 ), which is called 'slag'.

Mar 06, 2018Lime is basically calcium carbonate (CaCO3). The general source of lime is limestone and various other calcareous minerals, though shells, egg shells and coral are other sources of lime. When heated above 840 degrees Celsius, the lime decomposes into calcium oxide (CaO) or Quicklime and releases carbon dioxide (CO2).

How is limestone formed? What is limestone? Limestone

Diagenesis is the process by which soft sediments turn to rock. Limestones originate as soft lime muds, shells and other fragments of the organisms living in the water. When these sediments are buried under others, they are compacted, the water is squeezed out of pore spaces and, in some cases, mineral grains are physically re-organised or chemically changed by the pressure.
