What raw materials in the extraction of iron?
The raw materials used in the extraction of iron are iron ore, coke (made from coal), and limestone. Iron ore is the primary source of iron, while coke is used as a reducing agent and fuel, and limestone helps to remove impurities from the iron ore during the smelting process.
What are the limestone impurities?
Some common impurities found in limestone include clay, sand, iron oxides, and organic matter. These impurities can affect the color, texture, and overall quality of the limestone. Proper processing and purification of limestone can help remove these impurities and improve its suitability for various applications.
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.
What gases are passed through limestone?
Carbon dioxide and sulfur dioxide are commonly passed through limestone during processes such as flue gas desulfurization in power plants to help remove impurities and pollutants.
What three raw materials are used to make pig iron?
The three raw materials used to make pig iron are iron ore, coke (a type of coal), and limestone. Iron ore is the primary source of iron, coke is used as a fuel and reducing agent, and limestone helps remove impurities from the iron ore during the smelting process.
Why is limestone added to the blast furnace during the extraction of iron?
Limestone is added to the blast furnace during the extraction of iron to act as a flux. It helps to remove impurities, such as silica, from the iron ore by combining with them to form slag. The slag can then be easily separated from the molten iron.

What is the function of limestone in the furnace?
Limestone is added to the furnace as a flux to help remove impurities from the iron ore during the iron-making process. It reacts with the impurities to form slag, which can be easily removed from the molten iron.

Proper processing and purification of limestone can help remove these impurities and improve its suitability for various applications.
Why is limestone used in non ferrous metals?
Limestone is used in non-ferrous metal production as a flux, which helps remove impurities such as sulfur and phosphorous from the metal during the smelting process. It also helps to control the viscosity of the slag, improving the overall efficiency of the metal extraction process. Additionally, limestone can help in the reduction of energy consumption and enhance the quality of the final metal product.

Why limestone is used in the blast furnace?
Limestone is used in the blast furnace as a flux material to help remove impurities such as silica, which would otherwise form a slag that interferes with the smelting process. When limestone is added, it combines with the impurities to form a molten slag that can be easily separated from the molten iron.
What is added to the flux and form a slag?
Common additives to the flux, such as limestone or silica, react with impurities in the metal to form a slag. This slag helps to remove impurities from the metal during the refining process and is then removed from the surface of the molten metal.
What is the role of 70 ethanol in DNA extraction?
70% ethanol is used in DNA extraction to wash and precipitate DNA from a sample. Ethanol helps to remove impurities and salts, allowing DNA to clump together and be easily separated from the rest of the sample. It also helps to preserve the integrity of the DNA during the extraction process.
Which mineral is highly valued as an industrial flux?
Limestone is highly valued as an industrial flux due to its ability to help remove impurities from materials during the smelting process. It reacts with the impurities, forming slag that can be easily separated from the metal being produced.
Why is Limestone is used to purify sugar?
Limestone is used to purify sugar because it helps remove impurities like sulfur dioxide, which can affect the taste and quality of the sugar. Limestone reacts with sulfur dioxide to form calcium sulfite, which then precipitates out along with other impurities, leaving behind a purer sugar solution.
