Advantages of Our Iron Ore Pellets. Increase the Productivity of the Sponge Iron. Less fines generation in the DRI making due to its good physical and metallurgical properties. Consistent DRI & Blast Furnace Operation. Good Air permeability due to its uniformity in size. Better Quality of the Sponge Iron.

In this study, sponge iron ore concentrate (scale) and reductant (coke coal dust and sodium bentonite) were mixed at certain proportions to produce composite pellet samples; the effects of ...

1. Introduction. The Blaine number of iron ore concentrate is one of the most important parameters for controlling the pelletizing process in the iron and steel industry [1], [2], [3], [4].The specific surface area (SSA) of powder materials or Blaine number is defined as quotient of the available surface inclusive of all open inner surfaces divided by the …

Our iron ore pellets and fines are made from magnetite and have high iron ore content – pellets at around 67 percent concentration and fines over 70 percent. This means they …

The concentrate is supplied as a commercial product and used as a semi-finished product to make blast-furnace pellets and pellets for metallisation, and can also be used to make iron-containing briquettes. The development of technologies for injecting iron ore concentrate into furnaces through tuyeres (in combination with pulverised coal or ...

Iron ore must go through a lengthy pre-processing stage before it can be pelletized – a series of steps that work to beneficiate and concentrate low-grade ores. This process …

Iron ore pellets, like concentrates, are raw materials for the manufacture of iron, which is pulverized and ground into pellets ranging from 0 to 100 microns for supply to industry as pellet feed. Green pellets and hardened green pellets are used in the direct reduction process to produce iron. Raw materials for the production and production of ...

This study reported the extraction of vanadium from low-vanadium grade magnetite concentrate pellets using sodium salt. 71.1% of vanadium can be extracted under the following optimal conditions: pelletizing with 5 wt% Na 2 CO 3, preheating at 1050 °C for 10 min, roasting at 1250 °C for 10 min, and water leaching at 120 °C for 120 min …

These products relatively contain 64 to 72 percent iron and are not completely pure. ... Iron Concentrate; Iron Ore ...

DR Pellet Size Exceeds BF Pellet Size. DR pellets: >50 % + 12.5 mm vs. BF: 9.5 x 12.5 mm target. Benefits of larger pellets : Increase in permeability, increased yield ( fewer smaller pellets degrading into fines), reduced clustering tendency (with a decrease in contacting surface area) Drawbacks of larger pellets :

The iron ore concentrate is rolled in these drums to make pellets. Pellets are scrutinized and sorted according to their size specifications. The pellets that are over or undersized are crushed and returned to the balling drums. The pellets that are out of the balling drums are delivered to the roller feeder to remove the fines.
