Process The Corex process consists of two main parts a Reduction Shaft and a Melter- Gasifier.The main reagents for the Corex process are iron ore, noncoking coal, and oxygen. Unlike the Blast furnace the Corex process does not use a hot blast of nitrogen, thereby greatly reducing NOx gas emissions, but instead uses oxygen.
Blast furnace - Simple English Wikipedia, the free …
The process of making iron is simple. Iron ore is basically iron oxide. Iron is made by removing the oxygen. This leaves crude iron called pig iron. This process of removing oxygen is called smelting. Carbon is used in the reduction process, with the ore heated to
The FINEX Process :: Total Materia Article
The FINEX process, developed by Siemens VAI and POSCO is an innovative methodology in which molten iron is produced directly using iron ore fines and non-coking coal. The main benefits of the FINEX process include process efficiency, lower environmental impact, process simplifiion through removal of process steps.
Iron Ore Pelletizing Process: An Overview | IntechOpen
2017/7/10· The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing process

The MIDREX process is a shaft-type direct reduction process where iron ore pellets, lump iron ore or a coination are reduced in a Vertical Shaft (reduction furnace) to metallic iron by means of a reduction gas (see Figure 1.1.39) .
THE BLAST FURNACE - IRON PRODUCTION
The stock level is constantly ‘topped up’. Molten iron ore is ‘tapped’ at the bottom of the blast furnace, poured into the iron ladle and removed for use. The slag is removed at the tap hole. Although generally regarded as waste, it is used in road making.
Manufacturing Process of Cast Iron Castings
The making of cast iron begins with a coination of raw materials. Iron is rarely found in its pure form. Only meteorites contain pure iron. The iron in use for centuries is found in the coination of iron and other elements. These coinations are known as
