The first blast furnaces appeared in the 14th century and produced one ton per day. Even though equipment is improved and higher production rates can be achieved, the processes inside the blast furnace remain the same. The blast furnace uses coke, iron ore and limestone to produce pig iron. Coal is a key part of the coke-making process.

Forty-six per cent of Canada's iron ore comes from the Iron Ore Company of Canada mine, in Labrador City, Newfoundland, with secondary sources including, the Mary River Mine, Nunavut.
11.23.2 Process Description2-5,41 Processing of taconite consists of crushing and grinding the ore to liberate iron-bearing particles, concentrating the ore by separating the particles from the waste material (gangue), and pelletizing the iron ore concentrate. A simplified flow diagram of these processing steps is shown in Figure 11.23-1.
Iron ore fines are agglomerated into pellets and then indurated using a furnace to create iron ore pellets. These are typically fed to a blast furnace or DRI plant as part of the process to make steel. Expertise. Designed and supplied the largest straight grate systems in the world.
Pellets are obtained byadding an appropriate amount of water to the iron ore concentrate; this is a fundamental factor in the formation and growth of pellets, which creates a surface tension that holds the mineral grains cohesive, thus allowing their handling [6, 8].

crucible-like hearth. Iron-bearing materials (iron ore, sinter, pellets etc.), coke and flux (limestone and dolomite) are charged into the top of the shaft. A blast of heated air and also, in most instances, a gaseous, liquid or powdered fuel are introduced through openings at the bottom of the shaft just above the hearth crucible.
(CaO: 1.0 %, MgO: 1.4 % and C: 1.2 %) to make the reference pellet. First, the reference pellets were made taking iron ore fines of Blaine fineness 2855 cm 2/g as used in TSL, whose size fractions are given in Table 1. Then the prepared pellets were characterized in green and …
Iron ore pellet is a kind of agglomerated fines which has better tumbling index when compared with the iron ore and it can be used as a substitute for the iron ore lumps both in the BF and for DRI production.

2 Materials Used to make Steel 2.1 Iron Ore Composition Iron very rarely occurs in the earth's surface as a metal. It is widely distributed, combined with oxygen as iron oxides. In fact it is believed that iron makes up about 5% by weight of the earth's crust. Geologists recognise various types of iron ore, classified chiefly according to iron (Fe)

In the present invention, after a powdered iron ore has been subjected to granulation and firing into spherical pellets, a further crushing is applied while adjustment of the particle size of the crushed pellets is made so that the outer surface of the pellets is composed of spherically formed surfaces and crushed surfaces. By doing so, improvements are made in the angle of repose and in the ...
Iron ore is used mostly in pellet and/or lumpy form. Oxygen (O2) is removed from the iron ore by chemical reactions based on H2 and CO for the production of highly metalized DRI. In the direct reduction process, the solid metallic iron (Fe) is obtained directly from solid iron ore without subjecting the ore or the metal to fusion.
Iron ore pellets are spheres of typically 6–16 mm (0.24–0.63 in) to be used as raw material for blast furnaces.They typically contain 64–72% Fe and various additional material adjusting the chemical composition and the metallurgic properties of the pellets. Typically limestone, dolomite and olivine is added and Bentonite is used as binder..
