manufacture of lime from limestone process

Lime and Limestone

Lime products are generally the most readily available and most cost-effective alkaline chemicals and are used in a wide variety of industrial processes. In many countries, the largest use is for the production of iron and steel, followed by building and construction, environmental protection, and the chemical industry.

Lime (material)

Production. In the lime industry, limestone is a general term for rocks that contain 80% or more of calcium or magnesium carbonate, including marble, chalk, oolite, and marl. Further classification is done by composition as high calcium, argillaceous (clayey), silicious, conglomerate, magnesian, dolomite, and other limestones.

Lime and its Production

The Lime Cycle The lime cycle shows the stages from quarrying the limestone through to the production of mortars and plasters for our buildings and how it slowly, through the re-absorption of Carbon Dioxide, reverts to its original chemical form (Calcium Carbonate) in the wall.

What is the use of limestone of in the extraction of iron from

Answer: Usually, limestone (calcium carbonate, CaCO3) is “calcined" in a lime kiln, where it is heated to form lime (CaO) and CO2 gas. The lime is then used in both steelmaking furnaces to refine liquid iron into steel, and also on ladles as slag to further refine the steel.
