process of making iron ore
The Process Of Making Iron Ore Powder. This processing s to transform raw mined iron ore into a concentrated powder suitable for pelletiing. In addition to mined iron ore other sources of iron such as flue dust collected from blast furnaces or the dust produced at mine sites is also frequently pelletied so it can be utilied as opposed to

The main reason for the COREX process are iron ore, non-coking coal, and oxygen. Unlike the blast furnace the COREX process uses not air but oxygen. The second smelting reduction process is FINEX process which was developed by Siemens and POSCO as an innovative methodology in way molten iron is produced directly using iron or fines and non-coking coal.
Operating Line Prediction of COREX Iron-making …
The idea proposed by Rist was further utilized to perform the heat balance along with the net oxygen balance for the other iron making processes. The operating line has been modified thus accounting the generated H 2 O and CO 2 with respect to Fe, in the process of smelting reduction of ore by coal containing volatile and moisture.

6 Steps of Modern Steelmaking Process | 3MVET
Modern methods, however, are still based the same premise as the Bessemer Process, namely, how to most efficiently use oxygen to lower the carbon content in iron. Modern steelmaking can be broken down into six steps: 1. Ironmaking: In the first step, the raw inputs iron ore, coke, and lime are melted in a blast furnace. The resulting molten iron - also referred to as ''hot metal'' - still
