Unlike magnetite ore, pellet prepared from hematite ore requires more heat to attain a CCS of 50 kg/pellet (Fig. 2). Biswal et al. observed that the preheating temperature of 1050 °C is required to achieve the threshold CCS for a hematite ore whereas for a magnetite ore, the preheating temperature of 870 °C is adequate [13].

The iron ore fines were ground to below 150 μm using a laboratory ball mill (2 ft. x 2 ft) in closed circuit grinding. The particle size distribution of ground iron ore fine and slime samples were carried out by wet process using standard sieves (Table 1). It is observed that 95% of the slime particles are below 45 μm.

Deep dephosphorization of high‑phosphorus oolitic iron ore (HPOIO) is extremely difficult because of its refractory characteristics. A new approach for simultaneous iron recovery and dephosphorization from HPOIO by oxidation roasting gasbased reduction (ORGR) and magnetic separation process was developed. The underlying mechanism was investigated using thermodynamic calculations, Xray ...

Magnetite is a unique iron oxide that's often referred to as Lodestone. What sets it apart from other minerals is its magnetism, which is derived from its iron content. In the realm of geology, Magnetite serves as a crucial indicator for identifying ore deposits. It aids in the search for valuable resources like iron, gold, and copper.

Sakthivel et al in their work prepared magnetite powder using iron ore tailing. A fraction of the extracted FeCl 3 solution was changed into FeCl 2 via metallic iron formation using NaBH 4 as a reducing reagent. The magnetite particles synthesized in different ways showed varying degrees of magnetization behavior, credited to the change in ...

Thermal volume changes and oxidation mechanisms in magnetite iron ore green pellets balled with % bentonite binder, as a function of raw material fineness and pellet porosity, are shown. When a pellet starts to oxidize, a shell of hematite is formed around the pellet while the core still is magnetite. Dilatation curves were measured under nonoxidizing and oxidizing atmospheres to ...

Magnetite is an important, strongly magnetic iron ore, along with hematite. Nanoinclusions of magnetite crystals cause the iridescence of Rainbow obsidian (Nadin, 2007). Extremely thin layers of 200nm octahedral crystals of magnetite give some basalt surfaces an iridescent sheen (Nadin, 2007). May precipitate from supersaturated volcanic gas ...
