Limestone is a sedimentary rock composed mainly of calcium carbonate that is made up of different ratios of the following chemicals:. Calcium carbonate (CaCO3); Calcium oxide (CaO); Magnesium Oxide (MgO); Silicon dioxide or Silica (SiO2); Aluminum oxide or alumina (Al2O3); Iron (III) oxide or hematite (Fe2O3); Sulphate (SO3); Phosphorus …

Crystalline limestone is a carbonate sedimentary rock that is composed of the precipitation of the mineral calcite ((ce{CaCO3})) from saturated sea water. Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate ((ce{CaCO3})). About 10% of sedimentary rocks are limestones.

The limestone (calcium carbonate-CaCO 3) helps remove these impurities. The heat from the furnace decomposes the limestone: CaCO 3 (s) ———-> CaO(s) + CO 2 (g) The calcium oxide produced reacts with the silicon (IV) oxide to form a 'slag' of calcium silicate. This slag is used as a building material, especially in road building.

Limestone will react and fizz with a weak acid like white vinegar. Fossils, shell fragments, and coral are common. Because the overall appearance of limestone is so varied from one specimen to the next, physical tests are often the best way to identify it. These tests are designed to give an indication of the mineralogy of the rock, and in the ...

If raw limestone was used, its calcination would absorb heat from the process. Fluorspar is added to promote the fluidity of the slag. Any iron ore required (to adjust temperature) is then added with the remainder of the flux charge, whilst blowing continues. The complex flux charge is added within the first few minutes of the blow.
