Limestone | Types, Properties, Composition, Formation, Uses
Lithographic limestone is a type of limestone that contains fossils. Powered limestone is used in coal mines as a safety precaution because it absorbs pollutants. It can also be used on roofs to prevent or reduce weather or heat related roof damage. Its turns into the metamorphic rock marble when subjected to high amounts of pressure and heat.

Calcination of Limestone – IspatGuru
Limestone is generally classified into the two types namely (i) high calcium in which the carbonate content is composed mainly of CaCO3 with a MgCO3 content not more than 5 % (usually less), (ii) magnesium or dolomitic limestones which refers to a limestone containing MgCO3 at a higher level than limestone but less than dolomite and which contains MgCO3 in the range of around 5 % to 20 %.

Management of Lime in Steel
Limestone extraction is done by blasting, followed by crushing and screening. Depending on the chemical characteristics, limestone can be washed to remove the surrounding impurities such as clays. Calibrated stones size depends on the kiln type [3]. Finer-sized limestone can be used partially as raw material for self-fluxing sinters. Figure 1.

Blast furnace
Blast furnaces operate on the principle of chemical reduction whereby carbon monoxide converts iron oxides to elemental iron. Blast furnaces differ from bloomeries and reverberatory furnaces in that in a blast furnace, flue gas is in direct contact with the ore and iron, allowing carbon monoxide to diffuse into the ore and reduce the iron oxide.

SIZE REDUCTION 2. so separation can be carried out 1. occurs in sizes that are too large to be used • Large particles of solids are cut or broken into small pieces • reasons: 3. increases the reactivity 4. reduces bulk of materials for easier handling and for waste disposal in food-processing industry
Typical size of limestone for these types of kilns ranges from 25 mm to 40 mm. Uniformity of limestone size for charging the kiln is very important for a uniform calcining process. But, from a practical point of view, tight sizing is expensive due to the multiple screening required.
