Pelletizing is a process which involves mixing of very finely ground particles of iron ore fines having a size which is less than 200 mesh (0.074 mm) with additives like bentonite and then shaping them into near oval/spherical balls having size in the range of 8 mm to 16 mm in diameter by a pelletizer and hardening the balls by firing with a fuel.

Steelmaking has played a crucial role in the development of ancient, medieval, and modern technological societies. Early processes of steel making were made during the classical era in Ancient Iran, Ancient China, India, and Rome but the process of ancient steelmaking was lost in the West after the fall of the Western Roman Empire in the 5th century CE.

Abstract. Steel is an alloy of iron and carbon that is vital to the global economy. Its unique combination of strength, formability, versatility, recyclability, and low cost make it an ideal material for the construction industry, shipbuilding, motor vehicle manufacture, railway construction, bridge building, heavy industry, machinery manufacture, and engineering applications.

Iron processing - Iron processing - Ores: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is ...

Iron making. Iron ore is produced in around 30 countries – in 2017, the largest producers were Australia, Brazil and China. Around 98% of iron ore is used in steel-making. During the iron-making process, a blast furnace is fed with the iron ore, coke and small quantities of fluxes (minerals, such as limestone, which are used to collect ...

In his discussion of electric-furnace production of pig iron and pig steel before the Engineers' Society of Western Pennsylvania, Dr. J. W. Richards defines pig steel as "a metal with 2.2 per cent, or less of carbon, a very small amount of silicon and manganese, low in sulphur and phosphorus, and made directly from iron ore in the electric pig iron furnace."

The making of cast iron begins with a combination of raw materials. Iron is rarely found in its pure form. Only meteorites contain pure iron. The iron in use for centuries is found in the combination of iron and other elements. These combinations are known as iron oxides. Mining pulls most of the iron from iron ores ...

Iron and steel making by-products. As with all large-scale manufacturing processes, the production or iron and steel generates by-products. On average the production of 1 tonne of steel results in 200 kg (EAF) to 400 kg (BF/BOF) of by-products. The main by-products produced during iron and crude steel production are slags (90%), dusts and sludges.
