Its most important mineral forms are magnetite (Fe 3 O 4 , 72.4 Fe), hematite (Fe 2 O 3 , 69.9 Fe) and siderite (FeCO 3 , 48.29 Fe). In Brazil, some ore that contains practically no other minerals can grade as high as 68 Fe, but the crude ore mined in Canada grades between 30 and 44 Fe.
Jul 16, 2020 To enrich the iron share of the ore, for example through flotation and or magnetic separation, it is necessary to first grind the ore to a workable grain size.

Grinding. 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.Iron ore fines is a kind of ore fines which is made from iron ore (ore containing iron elements or iron compounds) through processing, such as ore processing, crushing, sorting, and grinding. The types of iron ore fines are mainly divided into magnetite fines, hematite fines, limonite fines, siderite iron silicate fines and sulfide iron ore.
Primary-route steel production, the high-grade iron ore market is growing in size and profile.
