processes, iron oxide contained in the iron ore is reduced by coke and it turns to iron containing carbon of slightly less than 5% (pig iron). This pig iron is processed by adjusting the components in various ways to make end products, such as sheets, plates, and ) As explained above, the steel industry handles large quantities of raw ...
The production of 1 ton of iron requires tons of ore or other iron bearing material; to tons of coke; tons of limestone or dolomite; and to 2 tons of air. Byproducts consist of to tons of slag, and to tons of blast furnace gas containing up to 100 pounds (lb) of dust.

At the Swedish plants, grinding is a wet process. In the Dutch plant grinding is carried out at relatively high temperatures (approx. 100°C). In the wet process additives (olivine, dolomite and/or limestone depending on the end product) are ground and then added to the ore slurry, typically at a level of 3 to %, before dewatering.

The shaft furnace (Figure 2) is the core of the DR process. Iron ore pellets are charged at the top, descend due to gravity, and encounter an upward counterflow of gas. The reducing gas (CO and H 2, plus CH 4, CO 2, and H 2O, at about 950 °C) is injected peripherally at midheight and exits at the top.

Jul 10, 2017· The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and lowgrade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing process ...
Aug 17, 1971· The paragraphs below briefly describe the process, starting with the wet process and then noting differences in the other processes. In the wet process and long dry process, all of the pyroprocessing activity occurs in the rotary kiln. Depending on the process type, kilns have lengthtodiameter ratios in the range of 15:1 to 40:1.
As the mixture of iron ore, coke and limestone heats, the hot waste gases are collected and cleansed. They are then used to help heat the air blast, required if blast furnace is to reach the high temperatures needed to produce molten iron. The stock level is constantly ''topped up''.
Iron ore must be shipped in bulk for maximum economy. Pretreatment process In this process, the iron ore is ground into fines having qualities required for the subsequent balling process. The pretreatment includes concentrating, dewatering, grinding, drying and prewetting. In general, lowgrade iron ore is ground into fines
Iron ore pellets are spheres of typically 6–16 mm (– in) to be used as raw material for blast 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.. The process of pelletizing combines mixing of ...
When the iron ore is extracted from the mine, it must undergo several processing stages. Six steps to process iron ore. 1. Screening. We recommend that you begin by screening the iron ore to separate fine particles below the crusher''s CSS before the crushing stage. A static screen is used to divert the fine particles for crushing.
