The amount of iron input as steel scrap into unit process No. 4 is s ton, where s < 1 ton.The amount of iron in the products of unit process No. 3 and its upper-stream unit processes will decrease to (1 − s) ton, see Fig. 2.Thus, the amount of natural iron resource input from the surroundings will be (1 − s) ton, and the amount of iron in the final product will also …
The converter in the BOS Plant turns the pig iron into steel. Here, we add oxygen and used steel, or steel scrap. Scrap ensures that the temperature in the converter does not rise too high and it is sustainable: empty tins, old cars, refrigerators and even bridges are reused. Steel is a pre-eminently circular product: it can be endlessly reused.
Sintering is a thermal process (carried out at 1300 deg C to 1400 deg C) by which a mixture of iron ore, return fines, recycled products of the steel plant industry (such as mill scale, blast furnace dusts, etc.), slag forming elements, fluxes and coke fines are agglomerated in a sinter plant with the purpose of manufacturing a sintered product ...

Abstract The state of the art for the recovery of metals from steel industry by-products using hydrometallurgical processes is reviewed. The steel by-products are different slags, dusts, and sludges from a blast furnace (BF), basic oxygen furnace (BOF), electric arc furnace (EAF), and sinter plant, as well as oily mill scale and pickling sludge. The review highlights that dusts and …
Iron ore handling, which may account for 20–50% of the total delivered cost of raw materials, covers the processes of transportation, storage, feeding, and washing of the ore en route to or during its various stages of treatment in the mill.. Since the physical state of iron ores in situ may range from friable, or even sandy materials, to monolithic deposits with hardness of …

Fig 3 Types of processing ores. The wet processing (Fig 4) is normally practiced for low / medium grade (60 % Fe to 63 % Fe) hematite iron ore. The wet process consists of multi-stage crushing followed by different stages of washing in the form of scrubbing and / or screening, and classification etc., but the advantage is only partial removal of adhered alumina …
Final process of 5 th phase is the final grinding. There is a horizontal filled with steel balls. Clinker reach in this rotating drum after cooling. Here, steel balls tumble and crush the clinker into a very fine powder. This fine powder is considered as cement.
Steel production is a 24-hour-a-day, 365-day-a-year process, dependent on a consistent supply of raw materials and huge amounts of energy. According to the World Steel Association, world crude steel production has increased from 851 million tonnes (Mt) in 2001 to 1,606 Mt in 2013 and world average steel use per capita has steadily increased from 150kg in …
