DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 °C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines. The reduction takes place using gaseous reductants (CO + H ...
Sponge iron: A metallic product made by direct reduction of iron, via the removal of oxygen from iron ore. Sponge iron is also known as DRI, or direct reduced iron Slab: Semi-finished steel product - the main intermediate material in the production of flat rolled steel.

Dec 14, 2013· Direct reduced iron (DRI) is also known as sponge iron. It is produced by the reduction of iron ore (in the form of lumps or pellets) by either non-coking coal or a reducing gas produced by reforming of natural gas. The reducing gas can also be produced by the gasification of coal. The reducing gas is normally a mixture.

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO ...
Mining companies use this reaction to obtain iron from iron ore: Fe2O3(s)+3CO(g) → 2Fe(s)+3CO2(g) The reaction of 177 g of Fe2O3 with 82.8 g of CO produces 72.7 g of Fe. Calculate the theoretical yield of solid iron. ANSWER: 110. g Fe. Read More

Iron Ore: In sponge iron making, iron ore is reduced in solid state. Unlike in the conventional steel melting processes, the gangue content of iron ore cannot be separated as a slag. Therefore, it becomes imperative to select an ore with a high Fe content and a low gangue content, to optimize yield .
iron ore creates lots of microscopic pores. These microscopic pores give the iron a sponge texture, therefore it is in another sense known as sponge iron [3] . HBI is currently produced via two major process routes. By one process route, reduced DRI pellets can be fed from the reducing furnace into a briquetting machine. Physically
Iron makes up 5% of the Earth's crust and is one of the most abundantly available metals. It is primarily obtained from the minerals hematite and magnetite. It can also be obtained from taconite, limonite, and siderite. Iron is the most used of all the metals. Iron is also found in meat, potatoes and vegetables and is essential for animals and ...
