Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite.Marble is typically not foliated, although there are exceptions.In geology, the term "marble" refers to metamorphosed limestone, but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. Marble is commonly used for sculpture and as a building material.

The vast majority of calcium carbonate used in industry is extracted by mining or quarrying. Pure calcium carbonate (such as for food or pharmaceutical use), can be produced from a pure quarried source (usually marble). Alternatively, calcium carbonate is prepared from calcium oxide.
Read on to discover the components of marble and the applications of its dust. Components of Marble. Calcium carbonate appears in such natural materials as limestone, gypsum, chalk, and marble. The mineral content of marble results from the original makeup of its rock mass, which often includes manganese, magnesium, and iron.
Nov 02, 2011· Marble is composed mainly of calcium carbonate, CaCo3. If 0.750g of marble reacts with hydrochloric acid to produce 165mL of carbon dioxide at STP, what is the percentage of calcium chloride in the sample? CaCo3 (s) + 2HCl (aq) --> CaCl2 (aq) + H2O (l) + CO2 (g)

How to Make Your Own Calcium Carbonate from Your Eggshells Step 1) First, rinse and save your shells. You should plan on having the shells from at least 18 eggs. You MUST consider the source of your eggs. The quality of the shell of your eggshells is only as good as the food the chickens eat and the environment in which they live.
Calcite as Limestone and Marble. Limestone is a sedimentary rock that is composed primarily of calcite. It forms from both the chemical precipitation of calcium carbonate and the transformation of shell, coral, fecal and algal debris into calcite during diagenesis.
Calcium carbonate is a chemical compound with the chemical formula CaCO3. It is a common substance found in rock in all parts of the world, and is the main component of shells of marine organisms, snails, pearls, and eggshells. Calcium carbonate is the active ingredient in agricultural lime, and is usually the principal cause of hard water.
