The heat test is a fundamental procedure to determine the calcium oxide (lime) content in limestone. The steps involved are as follows: Weigh a sample of dry limestone. Heat the sample for four hours in an open fire. Observe and record the reduction in weight after heating to calculate the calcium oxide content. 3.
Calcium Carbonate Formula. It is a chemical compound with the chemical formula CaCO 3.; It is a white insoluble powder-like substance which occurs naturally in minerals, chalk, marble, limestone, calcite, shells, pearl, etc.; Medicinally, it is used as an antacid or as a calcium supplement.
A few of its modern age uses are listed below –. For whitewashing – Slaked lime is used in whitewashing. It reacts with carbon dioxide slowly and forms a layer of calcium carbonate on the wall which gives shine to the wall. For manufacturing of sugar – Slaked lime is used in manufacturing sugar from sugar cane.

From stone to lime. Quicklime is extracted from limestone, a common rock found all over the world, which has formed over millions of years from deposits on seabeds. The most important component of limestone is calcium carbonate (CaCO 3 ), which is broken down into calcium oxide or quicklime (CaO) and CO 2, by the addition of thermal energy.
Limestone can also be chemical in origin as is the case with travertine. Chemical limestone forms when calcium and carbonate ions suspended in water chemically bond and precipitate from their aquatic sources. Because of its high calcium content, limestone is usually light in color, although many variations exist.
Limestone Drying Benefits. The drying process accomplishes many benefits for limestone such as: Enhanced Product Quality. Preconditioning a material for subsequent manufacturing stages creates a better final product. By correctly preparing the material at the very beginning, manufacturers ensure better limestone processing and improved ...
