1. Introduction. Iron ore pellets are one of the significant sources of iron for iron and steel making due to their superior metallurgical performance, low energy consumption, and less emission of environmentally harmful dust and gases during the production process [1], [2], [3].The two primary raw materials for pellet production are hematite and magnetite concentrates.

Magnetite is an iron oxide ore, which belongs to the equiaxed crystal system, and its chemical formula is Fe3O4. The Mohs hardness of magnetite is 5.5~6.5. Like hematite, it has strong magnetism. In ancient times, it was also called a magnet. Magnetite is often formed in igneous, …
Hematite and magnetite are the most commonly found iron ore minerals. The smelting process involves heating the iron ore with carbon. Carbon combines with the oxygen and removes it, leaving behind iron. ... allowing it to be drained off and poured into molds to form bars known as ingots. MINING AND PROCESSING: Iron ore mining can be broadly ...

Generally, the iron content of magnetite ore mined is 30%~60%, which is mainly used for iron making. Magnetite must be upgraded through the ore treatment process to produce high-grade concentrates for steelmaking. The most commonly used beneficiation method for magnetite is weak magnetic separation.

Iron ore pellets are made from both magnetite and hematite ores. Hematite ores are concentrated using a flotation process. Pellets include a mineral binder that represents about 2% by weight.
Fig. 4 shows the process stages of a possible iron ore beneficiation for magnetite ores or also siderite and taconite ores that have only a low to medium iron content. After comminution and screen sizing, the coarse ore and fine ore streams are treated separately. The coarse ore stream is fed to a DMS trommel and then wet screen classification.
Magnetite is rock mineral and one of the most important iron ore minerals with chemical formula is iron(II,III) oxide, Fe2+Fe3+2O4 .It also as the name magnetic minerals to attracted to a magnet. It is the most magnetic natural occuring minerals in the World. Small grains of magnetite occur in almost all igneous and metamorphic rocks.. Magnetite, Balmat, Balmat …
Iron ore magnetite processing (LIMS, MIMS, WHIMS, Davis Tubes) The increased worldwide demand for steel in recent decades has led to an increase in the exploitation of magnetite iron ore deposits as an alternative to hematite DSO ores. Magnetite concentrate is a higher-grade product than hematite and very desirable as a smelter feed.

The iron oxide mineral magnetite as Fe 3 O 4 has a mass percent of 72.36% Fe and 27.64% O and typically occurs as a natural ore containing 15–40% Fe. Historically hematite direct shipping ore (DSO) has been the preferred source of iron ore globally, with significant resources located on several continents, including Australia in the Hamersley Range, Western Australia.
