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 than that used for sintered ore. The ore fine is formed into spheroids, called green balls, approximately 12mm in diameter. The green balls are fired into product pellets. The pellets ...

The ore must be ground to a particle size sufficiently close to the grain size of the iron-bearing mineral to allow for a high degree of mineral liberation. Most of the taconite used today requires very fine grinding. Prior to grinding, the ore is dry-crushed in up to six stages, depending on the hardness of the ore. One or two stages of crushing may be performed at the mine prior to shipping ...

Through crushing, grinding, and various other techniques, low-grade iron ore is frequently upgraded to a concentrate product in the form of a powder. If processed directly, this powder would reduce the efficiency of the overall steel making process, including blast furnace performance; therefore, pelletizing of the fines is essential to process efficiency.

Iron ore pellets can be made from beneficiated or run of mine iron ore fines. Lean iron ores are normally upgraded to a higher iron ore content through beneficiation. This process generates iron ore filter cake which needs to be pelletized so that it can be used in an iron making process. Also during the processing of high grade iron ores which do not need beneficiation, generated fines can be ...
