They contain 64-72% iron and additional materials, which can adjust the chemical composition and metallurgical properties of the pellets. The iron ore pelletization is the process of converting iron fines less than 200 mesh (0.074 mm) into 8-16 mm pellets. Types of iron ore pellets Iron ore pellets are normally produced in two types …
Ore car dumping Once the train arrives at the port the ore cars go through the car-dumper. The ore cars are rotated and the ore flows out into bins and then is discharged onto conveyors. Stockpile The ore is stockpiled according to product type and the quality control plan. The travelling stackers create 250m long stockpiles. Rotary bucket-wheel
Best-in-Class Steel Producer. Cleveland-Cliffs is the largest flat-rolled steel producer in North America. Our competitive advantage as an integrated steel company is based on our ability to operate the entire production flow from the extraction of iron ore, to steelmaking, rolling, coating, finishing, stamping and tooling steel products.
Beneficiation of Iron Ore and the treatment of magnetic iron taconites, stage grinding and wet magnetic separation is standard practice.This also applies to iron ores of the non-magnetic type which after a reducing roast are amenable to magnetic separation. All such plants are large tonnage operations treating up to 50,000 tons per …

Many flow sheets have been developed and can generally be divided into wet or dry circuits based on the feed moisture and open or closed circuits …
An iron ore pelletizing plant is typically comprised of a series of unit operations in a specific process sequence. It can be divided into: Feed preparation; Mixing (Iron ore + additives) Balling ("green" pellets are produced) Indurating (firing and hardening and producing the "fired pellets")
Whether straight grate or Circular Pelletizing Technology, plant design starts with the raw material. Profound knowledge of iron-ore characteristics, including variances in chemistry and regional factors, is key to creating the ideal pelletizing plant for high-quality pellets.
The iron ore pelletizing process consists of three main steps: 1. Pelletizing feed preparation and mixing: the raw material (iron ore …
The quality of these materials has direct bearing on the process as well as the product. Some plants do not use iron ore directly. These plants use iron ore pellets in the rotary kiln. Raw material mix consisting of iron ore, dolomite and non-coking coal is fed at the one end of the rotary kiln and is heated by coal burners to produce DRI.

It is one of the company's leading sources of iron ore for operations in the United States. Iron ore is a major raw material required in the manufacturing of steel. Iron-bearing pellets are shipped to Cleveland …
Following are the changes to be implemented for smooth operation of the existing plant at 2mtpa capacity. a) Feed Ore Quality: Quality of Iron Ore feed to pellet plant is very important to get desired product quality. Iron ore better than 63% 'Fe' content shall be used to make pellets, which will have good metalisation properties.

Direct reduction of hematite pellets with hydrogen (H2) was used to produce directly reduced iron (DRI) in a pilot scale reactor at a pellet feed rate of 21.4 kg/h. At a steady state, operational parameters of the pilot plant (gas recycling rate and inlet temperature) along with key reactor output parameters, the pellet metallization, and the …
include iron scrap, reduced iron pellets and reduced iron briquettes. Sintered ore is made by partially melting and sintering coarse iron ore 1 to 3mm in size into products having a size of 15 to 30mm. The sintering process uses the combustion heat of coke breeze (fuel). Pellets are made from iron ore that is finer

ABSTRACT. The behavior of iron ore pellet binders is complex. Any pellet binder is subject to a handful of practical requirements: that it be readily dispersed through a pellet, that it effectively controls the movement of water within the pellet, and that it contributes to the inter-particle bonding within the pellet.
Vale S.A. is a Brazilian multinational diversified metals and mining corporation. In addition to being the second-largest mining company in the world, Vale is also the largest producer of iron ore pellets. Vale S.A opened a 9 MTPA (2 x 4.5) Iron ore pellatisation plant in Sohar, Sultanate of Oman., on March 3rd, 2011. High
The sponge iron is melted into the actual crude steel. This process will be discussed in more detail in the next section. In the direct-reduced iron (DRI) process, the iron ores are reduced directly to …
1.3 Charging the blast furnace/ BOS plant Pellets are primarily used in blast furnaces and are also used in DR-plants. Occasionally pellets are used in the steel process. Pellets are stored in bunkers before charging to the blast furnace. The mixture of iron bearing materials (iron ore rubble, sinter and/or pellets) and additives (flux material)
