Sintering: A Step Between Mining Iron Ore and Steelmaking
The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is the primary feed material for making iron and steel in a blast furnace.
The Sintering Process of Iron Ore Fines – IspatGuru
Mar 09, 2013 · The principle of sintering involves the heating of iron ore fines along with flux and coke fines or coal to produce a semi-molten mass that solidifies into porous pieces of sinter with the size and strength characteristics necessary for feeding into the blast furnace.
Sinter plant - Wikipedia
Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace. The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals. The process, called sintering, causes the constituent materials to fuse to make a single porous mass with little change in the stone properties of the ingredients. The purpose of sinter are to be used converting iron into steel.
Iron Ore Sinter - an overview | ScienceDirect Topics
Iron ore sinter typically constitutes more than 60% of the blast furnace ferrous burden in modern blast furnaces in East Asia. Granulation and thermal densification are two important steps in iron ore sintering and determine the quality of the resultant sinter and the performance of the sintering process.

Blast furnace - Wikipedia
Blast furnaces differ from bloomeries and reverberatory furnaces in that in a blast furnace, flue gas is in direct contact with the ore and iron, allowing carbon monoxide to diffuse into the ore and reduce the iron oxide to elemental iron mixed with carbon.
Ore Sintering - an overview | ScienceDirect Topics
The sintering process begins with the preparation of a sinter mixture consisting of iron ore fines, fluxes, solid fuel (called bonding agents in Japan) such as coke breeze, and return fines from the sinter plant and blast furnace as well as recycled ferruginous materials from downstream iron …
Blast furnace | metallurgy | Britannica
Blast furnace, a vertical shaft furnace that produces liquid metals by the reaction of a flow of air introduced under pressure into the bottom of the furnace with a mixture of metallic ore, coke, and flux fed into the top. Blast furnaces are used to produce pig iron from iron ore for subsequent processing into steel, and they are also employed in processing lead, copper, and other metals.
HOW A BLAST FURNACE WORKS - Foundry Gate
HOW A BLAST FURNACE WORKS Introduction The purpose of a blast furnace is to chemically reduce and physically convert iron oxides into liquid iron called "hot metal". The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom.
Iron Ore to Sintering to Steelmaking - Analyzing Metals
Sinter is the primary feed material for making iron and steel in a blast furnace. We recently wrote about sintering in our sister blog, Advancing Mining . Read the article to learn more about how sinter quality begins with the mined iron ore and the proper selection and mixing of the raw materials.

Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources ...
Ironmaking 101 – From Ore to Iron with Blast Furnaces ...
Ironmaking Blast Furnace. Iron is made by reacting iron ore (iron oxide and impurities), coke (a reductant) and limestone (CaCO 3) in a blast furnace.. Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities.
Sinter | Definition of Sinter by Lexico
‘typical blast-furnace burdens are 80% sinter, 20% ore’ More example sentences ‘For decades, steelmakers have used highly polluting ovens to turn powdery coal and iron ore into chunks called coke and sinter, which are melted with superheated air to make iron.’
