How is limestone formed? | What is limestone? | Limestone

Limestone is a sedimentary rock It forms predominantly on the sea floor where material rich in calcium carbonate ('calcareous' material) accumulates This calcareous material may be organic, chemical or detrital in origin The sediment that goes to make up limestone may have been derived from the dead remains of marine organisms such as:May 02, 2013· Some limestone, due to its crystalline structure, disintegrates during the calcination process This type of limestone is not useful for calcining There is some other limestone whose behavior is the opposite This type of limestone become so dense during calcination that it prevents the escape of CO2 and become non porousCalcination of Limestone – IspatGuru

How Does Acid Rain Wear Away Limestone Answers

Limestone, or calcium carbonate, is insoluble in pure water However, in an acidic aqueous solution (such as acid rain), calcium carbonate is appreciably more solubleMarble is formed from limestone when the limestone is affected by heat and high pressure during a process known as metamorphism During metamorphism the calcite limestone recrystallizes, forming the interlocking calcite crystals that make up the marbleHow Is Marble Formed From Limestone? | Reference

How Does Weathering Affect Limestone? | Reference

Weathering creates underground caves and passages in limestone in addition to depressions and other unusual dips and grooves on the surface Karst is landscape formed from the weathering of limestone Limestone is a sedimentary rock created from the remains of dead sea creatures and is predominately made up of calcium carbonateLimestone is a source of calcium carbonate and is heated to convert the calcium carbonate into calcium oxide This process is generally carried out in large rotary kilns or vertical shaft kilns where high temperature is required Quicklime is produced in the calcination process, which can be crushed depending on it's useLime Production from Limestone Current Technology
