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 lowgrade 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 process of extracting iron from its ore involves crushing the ore to a powder and then heating it in a furnace with a carbon source. The carbon reacts with the oxygen in the ore to create carbon dioxide gas, which leaves the furnace through the smokestack. The molten iron is then poured into molds to cool and solidify.

World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. 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.

Abstract. In iron making process, sintering of iron ore fines is an integral step to utilize not only the ore fines but also to introduce a part of flux (limestone and dolomite) along with the sinter in blast furnace burden. In this way, the productivity of the furnace considerably improves. In this paper, some fundamental aspects such as the ...

The term blast furnace comes from the blast of hot air that is blown into the lower part of the furnace at between 1400º to 2100ºF. Molten iron is produced in a blast furnace by the following steps: 1. Charge (solid iron ore, coke, and limestone) is constantly dumped into the top of the furnace. 2.

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 highgrade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine granulometry is produced, and thus iron agglomeration ...

Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together. For this purpose, a travelinggrate machine is used, and the burning of fine coke (known as coke breeze) within the ore generates the necessary heat.
