Magnetite ore concentrate gets re-converted into hematite ore in the pelletisation, as it is an oxidation process. The hardening of pellets can be done by the vertical shaft kiln or travelling grate furnace cum rotary kiln. The vertical shaft kiln needs lower investments &is suitable for small capacities of 100,000 tons to 600,000 tons per year.

A new route for making steel from iron ore based on the use of hydrogen to reduce iron oxides is presented, detailed and analyzed. The main advantage of this steelmaking route is the dramatic reduction (90% off) in CO2 emissions compared to those of the current standard blast-furnace route. The first process of the route is the production of hydrogen by water …

Shaft furnaces are more energy efficient than the traveling grate or grate-kiln systems. The shaft furnace is well suited for pelletizing magnetite, but not hematitic or limonitic ore materials. Disadvantages of shaft furnaces are low unit productivity and difficulty in maintaining uniform temperature in the combustion zone.

Referring to the drawings, a vertical shaft type indurating furnace of a type well known in the art is generally designated 10. The furnace is generally rectangular in horizontal cross-section and may be considered as having two separate vertical sections made up of an upper heating stove 12 and a lower cooling stove 14.

plants and new plants use the grate/kiln. Currently, natural gas is the most common fuel used for pellet induration, but heavy oil is used at a few plants, and coal and coke may also be used. In the vertical shaft furnace, the wet green balls are distributed evenly over the top of the slowly descending bed of pellets.
