Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil "

Sponge iron is another form of iron that is produced directly from iron ore through a reduction process. This is why it is also called direct reduced iron. The ore is subjected to various reducing agents such as natural gas or gas that emits from coal. Sponge iron can even be produced from many types of furnaces such as blast furnace, charcoal .

· iron ore washing charges per cubic meter in india New CDE iron ore washing plant installed in Orissa, India . A new CDE Iron Ore washing plant has recently been installed in Orissa, India, on a site belonging to the Adhunik Group one of Indias largest steel producers.

Jun 14, 2011· Iron is extracted from its ore through removal of oxygen, which is a process called its reduction. Another process is through blast furnace where the ore is heated with carbon (coke). Iron thus produced using coke in blast furnaces is called pig iron, while iron produced through direct reduction is called sponge iron.

An iron ore reduction process which comprises the steps of maintaining an electric arc in a combined reduction and melting zone, feeding iron oxide ore through a prereduction zone and thence into said combined reduction and melting zone in close proximity to said arc, introducing molecular hydrogen into said combined reduction and melting zone and thermally decomposing the same by means of said are .

It can be inferred from Figure 12(a), the points inside " " within the curve of double " " characterized that the smelting reduction system came into the stage of interfacial chemical reaction control, the reduction process of iron ore generally came into the stage of chemical reaction control at low temperature phase ; it can be inferred from Figures 12(b), 12(c), and 12(d) that points outside " " characterized the system .

The reduction of iron oxides has been the subject of a prodigous amount of research as attested by the literature reviews of Specht and (1), Themelis and Gauvin (2), and Dutilloy, Ghosh and Rist

Reduction of carbon composite iron ore hot briquette takes place by heating only, and is assumed to provide excellent reduction performance, but no report has been yet made on reducing and melting behaviors of carbon composite iron ore hot briquette of by heating in shaft furnace.

completely dissolved. Note that the product of this reaction is FeCl3, and the iron is in the Fe3+ oxidation state. But the titration reaction requires Fe2+ so the iron must be reduced before it can be titrated. This is referred to as pre‐reduction. Have everything set up so that the pre‐reduction of the iron and the ceric ion
