Types of iron ore • The most commonly used type is Iron Ore Fines (generally known as Sinter Feed) which is sintered at the receiving steel mill, prior to being charged to the blast furnace. Iron Ore Fines typically have particle size up to mm. Fluidised bed direct reduction processes use Iron Ore Fines as their feedstock. •
Recycling this steel accounts for significant energy and raw material savings: over 1,400 kg of iron ore, 740 kg of coal, and 120 kg of limestone are saved for every 1,000 kg of steel scrap made into new Footnotes. 1. Sustainable Steel: At the core of the green economy,, worldsteel, 2012.

In summary, it is concluded that the Muko iron ore has good physical and metallurgical properties to serve as a natural material for the blast furnace and direct reduction furnaces. The blast furnace is still the dominant form of iron production, but over the years, direct reduction methods have increased due to a number of reasons.
Reduction: lronmaking Iron ore, as mined, is a combination of iron with oxygen and various other unwanted substances, generally known as "gangue". The first metallurgical step is to reduce iron ore to metallic iron, a process which is mostly carried out in a blast furnace, using coke .
In the face of shrinking world reserves of highgrade ores, ores must now be concentrated before further processing. Pelletizing turns very finegrained iron ore into balls of a certain diameter, also known as pellets, which are suitable for blast furnace and direct reduction. Pellets form one of the best options, thanks to their excellent physical

Sep 18, 2018· Abstract. Characterization and beneficiation of dry iron ore processing plant reject fines of Khondbond region, India, was investigated. Different characterization techniques viz. size analysis, sizewise chemical and density analysis, Xray diffraction analysis, sinkfloat analysis, thermo gravimetric analysis, scanning electron microscopy, and QEMSCAN were carried out.
Iron ore is the source of primary iron for the world's iron and steel industries. It is therefore essential for the production of steel, which in turn is essential to maintain a strong industrial base. Almost all (98%) iron ore is used in steelmaking. Iron ore is mined in about 50 countries.
While BIF has a low iron content with its magnetic iron ore (magnetite), it can be readily enriched from 32 per cent iron to 70 per cent. DRI requires a highgrade ore that requires beneficiation of the ores to reduce the silica and alumina to between 2 and 3 per cent.
