What qty of iron ore and coal be used in the production for getting 1 metric ton of sponge iron?
coal throw pipe adjustments
Is propane used as feedstock for sponge iron?
No, propane is not typically used as a feedstock for producing sponge iron. The most commonly used feedstock for sponge iron production is natural gas or coal. These feedstocks provide the necessary carbon and heat required for the direct reduction process to convert iron ore into sponge iron.

Can sponge iron making is a primary metallurgical process - yes or no?
Yes, sponge iron making is a primary or can be a primar metallurgical process base on the Chemistry information that is provided.
How do you purify coal?
Coal can be purified through a process called coal washing, which involves crushing the coal and using water and gravity separation to remove impurities like sulfur and ash. Flotation can also be used to separate impurities from coal by bubbling air through a mixture of coal and water. Magnetic separation can be used to extract iron and other metal impurities from coal.
How do you found Fe total of sponge iron?
Measuring the mass of sponge iron.
How do you reduce phosphorus and sulphur from sponge iron fines?
Sulfur in Sponge Iron comes from coal feeding. This sulfur when combustion with heat creates Sulfuric acid which is harmful to atmosphere. So to reduce sulfur you can used dolomite or lime stone. For 1 MT Iron ore you have to use 50 kg dolomite/lime stone.
What is the relation between metallic iron and total iron in sponge iron?
Metallic iron refers specifically to the iron that is in its metallic form in sponge iron. Total iron in sponge iron includes metallic iron as well as any iron present in other forms such as iron oxides. Therefore, metallic iron is a subset of total iron in sponge iron.
What is the chemistry of producing sponge iron in coal based DRI plant?
3Fe2O3 + C =2Fe3O4 + CO Fe304 + C = 3Fe0 + CO FeO + C = Fe + CO 3Fe2O3 + CO = 2Fe3O4 + CO2 Fe3O4 + CO =3 FeO + CO2 FeO + CO = Fe + CO2 and C + CO2 = 2CO In this ways iron oxide get reduced to iron which is called sponge iron.
Difference between pig iron and sponge iron?
http://encarta.msn.com/encyclopedia_761559225/iron_and_steel_manufacture.html Provides the answer. basic summary: 1. Pig Iron and Sponge Iron are the result of different production processes 2. Which results in different purities. Pig Iron has a lower purity than Sponge Iron.
How do you produce sponge iron powder?
Sponge iron powder is produced through the direct reduction of iron ore, typically using natural gas or coal as a reducing agent. The iron ore, often in the form of pellets or lumps, is heated in a reduction furnace at temperatures around 800-1,200°C, where it undergoes a chemical reaction that removes oxygen, resulting in sponge iron. This spongy material is then further processed and milled to produce fine iron powder. The final product is characterized by its high purity and low impurities, making it suitable for various applications in metallurgy and powder metallurgy.
What is the difference between Sponge iron and pig iron and their application?
Sponge iron is produced by reducing iron ore pellets in a direct-reduction process, whereas pig iron is produced by melting iron ore with a high-carbon fuel in a blast furnace. Sponge iron is mainly used as a raw material for steelmaking in electric arc furnaces, whereas pig iron is typically used in the production of cast iron and wrought iron products.
