Prereduced sinter or pellets used for subsequent processing are often sponge iron.
Extracting More Sponge Iron Is Imperative To Boost Steel
The major raw materials required for iron and steel production are iron ore, coal, limestone, water and energy. Most of the steel produced at present in the world is through Blast Furnace (BF) Basic Oxygen Furnace (BOF).

Iron ore–coal composite pellets/briquettes as new feed
The iron orecoal/coke composite briquette/pellet can be acted as new feed materials for iron and steel making. Since composite briquette/pellet have very fast reduction rate due to intimate contact between reductant and oxide particles, hence productivity of iron and steel making has drastically increased.Sponge Iron SpringerLink,Sponge iron means porous iron produced by direct reduction process.Direct reduction (DR) process is a solidstate reaction process (i.e. solid–solid or solid–gas reaction) by which removable oxygen is removed from the iron ore, using coal or reformed natural gas as reductants, below the melting and fusion point of the lump ore or The Effects of Volatile Materials of Noncoking Coal on ,3 Iron and Steel Research Center, Ferdowsi University of Mashhad, Mashhad, Iran Abstract One of the most important methods to produce sponge iron is coal based reduction of iron ore.

Iron ore BHP
There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, bright yellow, or deep purple to rusty red. Iron is responsible for the red colour in many of our rocks and the deep red sands of the Australian deserts.Rotary Kiln Process of Making Sponge Iron New Age ,2.6.1 Process Strengths.
