Where does steel come?
Smelting coal, iron ore, and limestone.
Why is limestone added as a raw material to the furnace?
Limestone is added as a raw material to the furnace primarily to act as a flux in the iron and steel-making process. When heated, it decomposes to produce lime, which helps to remove impurities such as silica and alumina by forming a slag that can be easily separated from the molten metal. This not only enhances the quality of the final product but also protects the furnace lining from damage. Additionally, the use of limestone can help improve the efficiency of the smelting process.
Is limestone a nonrenewable or renewable resource?
Limestone is a nonrenewable resource everyone so use your limestone wisely ! (:
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 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.
Where does steel come from?
Smelting coal, iron ore, and limestone.

Is limestone used for smelting iron ore and making cement?
Yes, limestone is used in both processes. In smelting iron ore, limestone acts as a flux to remove impurities from the ore. In cement production, limestone is one of the main ingredients, along with clay or shale, to make clinker that is then ground into cement.
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.
How do you use smelting in a sentence?
The blacksmith spent hours smelting iron ore to create a new sword.
What chemicals are used when smelting?
In the process of smelting, various chemicals are used depending on the ore being processed. Common chemicals include limestone (calcium carbonate) to act as a flux, silica (silicon dioxide) to remove impurities, and carbon (in the form of coke) to act as a reducing agent. These chemicals help in separating the desired metal from the ore during the smelting process.
Were do you find smelting job?
You might find a smelting job by searching for jobs near mines or copper pits. You could also use a head hunter or a job search service to find a smelting job.
What is the process of iron smelting?
Iron ore is not normally smelted, instead it is reduced in a blast furnace with a mixture of coke & limestone. The coke burns removing the oxygen from the iron ore and melting the resulting iron. The limestone neutralizes acidic sulfur compounds and acts as a flux.
How is limestone important to coal mines?
Limestone is important for coal mines because it helps to neutralize acidic water that can be produced during the mining process. This can prevent environmental damage by reducing the acidity and potential heavy metal contamination of water sources. Additionally, limestone can be used as a flux in the process of smelting coal to produce coke, which is essential for steel production.

What was limestone used for in the olden days?
It was cut into blocks for use as dimension stone in building, broken for use as rubble (in building and for fill), crushed for gravel and for a lightweight aggregate, burned for lime to make mortar and concrete, used as a flux in smelting, and used as a fertiliser to "sweeten" acid soils. And sometimes thrown at rabbits.
