JordanQuicklime is created from limestone through a process called calcination. The chemical equation for this process is: CaCO3 (limestone) -> CaO (quicklime) + CO2 (carbon dioxide). It involves heating limestone to high temperatures, around 900-1000°C, to drive off the carbon dioxide and produce quicklime.

What mass of quicklime can be made from 1 ton of limestone?
Approximately 0.56 tons of quicklime can be made from 1 ton of limestone. This conversion is based on the typical composition of limestone, which is primarily calcium carbonate. During the process of heating limestone to produce quicklime, carbon dioxide is released, leading to a reduction in mass.
What reaction takes place to produce quicklime?
Thermal Decomposition is the name of the reaction to produce quicklime from limestone.
How do you get from quicklime to slacked lime?
Quicklime is produced by heating limestone, while slaked lime is formed by adding water to quicklime. This process, called hydration, results in the formation of calcium hydroxide, also known as slaked lime.
What is the purpose of limestone in the blast furnace?
Limestone is added to the blast furnace as a flux material. It helps to remove impurities in the iron ore by forming a molten slag that floats on top of the molten iron. This slag can then be easily separated from the iron.
How do you make cement with limestone?
To make cement with limestone, you need to heat a mixture of limestone and clay in a kiln to about 1400°C, which produces a chemical reaction called calcination. This process breaks down the limestone into calcium oxide (also known as quicklime) which is a key ingredient in cement production. The quicklime is then mixed with other materials such as sand and water to create the final cement product.
