Corex Process for Production of Iron – IspatGuru

Corex process distinguishes itself from the blast furnace route by (i) direct use of non-coking coal as reducing agent and energy source, (ii) Iron ore can be directly and feasibly charged to the process in form of lump ore, and pellets, and (iii) use of pure oxygen instead of nitrogen rich hot blast. Direct use of non-coking coal is possible since the coal is charred inside the melter ...

Sponge Iron - an overview ScienceDirect Topics

Recently a variant of COREX process, FINEX, is codeveloped by VAI and Posco for the production of hot metal based on the direct use of iron ore fines and noncoking coal. Fine iron ore is charged into a series of fluidized-bed reactors together with fluxes. The iron ore fines pass in a downward direction through four reactors where they are heated and reduced to DRI by means of a reduction gas ...

The reasons for the success of Sponge Iron Industry in India

The slowdown in EAF steel production impacted domestic sponge iron production. Simultaneously, sponge iron production was also plagued with several issues such as the iron ore mining ban in India made it difficult to source raw material and the decline in steel scrap prices made scrap economically viable. The iron ore mining was banned in Karnataka (July 2011) and Goa (September 2012) because ...

Corex Process - Wikipedia

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. In addition, the Corex process can use iron oxides containing up to 80% lump ore and uses non coking coal directly as a reducing agent.
