What is the role of lime or limestone in the extraction of …
The chemical formula of limestone is CaCO 3. Limestone is a basic flux that can be used to form fusible slag from earthly impurities present in the ore. Limestone undergoes decomposition to form lime i.e. Calcium oxide (CaO) and Carbon dioxide. The decomposition reaction occurs as follows: CaCO 3 s Limestone → CaO s (Lime) + CO 2 g

How limestone ore is processed?
The processing of limestone ore typically involves extraction, crushing, grinding, and calcination. Extraction refers to the process of removing the limestone from the earth's surface or underground.

3. The Bayer Process The extraction of metals from their ores is commonly achieved via two processing routes: hydrometallurgy (where the metal is selectively dissolved in a liquid – usually water-based) or pyrometallurgy (where heat is applied and the metal may be in molten form). Sometimes a combination of the two routes is applied.

Extraction and processing
Extraction and processing. Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestone, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.

Limestone
Limestone. Limestone is a sedimentary rock composed mostly of the mineral calcite and comprising about 15% of the Earth's sedimentary crust. It is a basic building block of the construction industry (dimension stone) and a chief material from which aggregate, cement, lime and building stone are made. 71% of all crushed stone produced in the U.S. is either …
How Lime is Made
The limestone is heated as it moves down the kiln toward the lower end. As the preheated limestone moves through the kiln, it is "calcined" into lime. The lime is discharged from …
Limestone: The Calcium Carbonate Chemical Sedimentary Rock
Limestone, as used by the minerals industry, is any rock composed mostly of calcium carbonate (CaCO 3 ). Although limestone is common in many parts of the United States, it is critically absent from some. Limestone is used to produce Portland cement, as aggregate in concrete and asphalt, and in an enormous array of other products, making it …
