Metalization in sponge iron is calculated by measuring the percentage of iron content in the sponge iron compared to the total iron oxides present in the feed material. The formula used is:
[ \text{Metalization (%)} = \left( \frac{\text{Weight of metallic iron in sponge iron}}{\text{Weight of total iron oxides in the feed}} \right) \times 100 ]
For example, if you start with 100 kg of iron ore containing 70 kg of iron oxides, and the produced sponge iron contains 55 kg of metallic iron, the metalization would be:
[ \text{Metalization} = \left( \frac{55 , \text{kg}}{70 , \text{kg}} \right) \times 100 \approx 78.57% ]
It is the ratio of metallic iron to the total iron ,convert in percentage
The yield of production of sponge iron is calculated by dividing the weight of sponge iron produced by the total weight of iron ore initially taken for the process, and then multiplying by 100 to get the percentage yield. It is important to consider losses during the process to get an accurate yield calculation.
To calculate total iron in sponge iron when the metallic iron content is known, you can use the formula: Total Iron = Metallic Iron × (1 + Iron Oxide Ratio). The iron oxide ratio reflects the proportion of iron present in the form of oxides, which can vary based on the production process. For example, if you have 90% metallic iron and an oxide ratio of 0.1, the total iron would be calculated as 90% × (1 + 0.1) = 99%.
Measuring the mass of 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.

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.
Yes, sponge iron making is a primary or can be a primar metallurgical process base on the Chemistry information that is provided.
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.
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.
