The beneficiation of iron ore slime in the Brazilian scenario is a challenging task as it contains a significant amount of silicates, goethite and clay minerals (kaolinite and gibbsite) (Lima and Abreu, 2019). ... Fe, SiO2, P, Al2O3, Mn, …

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.

Chitradurga iron ore slime. In case of Ukraine iron ore slime hematite and goethite are the main iron bearing phases and quartz is the main gangue phase. Clay was found to be negligible in this sample. Fig. 2: Photomicrographs of Iron Ore Slimes. (A) Chitradurga Iron Ore Slime, (B) Jilling Iron Ore Slime, (C) Ukraine Iron Ore Slime

A generic method for quantitative estimation of mineral phases in ores and process streams has been illustrated in this paper with the help of an example taken from our own work on the selective flocculation of alumina rich iron ore slimes. The method used conventional bulk chemical assay data and information on phases present, as determined by powder X-ray …

Iron ore slime is a powdery material of very fine size (<50 µm) generated during washing of iron ores. Despite of high iron oxide content, it can't be used in the iron making process because of its higher alumina and silica content. In recent times, we have developed the process of making briquettes from iron ore slime as a coolant to replace iron ore lump in basic …

A typical high-alumina containing iron ore slime from the eastern Indian sector containing 58.13% Fe, 6.48% SiO2, 4.9 % Al2O3 and 5.35% LOI, have been evaluated to find out whether grinding of the ...

The scenario in iron ore mining industry is not different. Slime generated during washing of iron ores (to remove the associated powdery materials) is a concern for the iron ore mining industry. Typical slime generation is around 20% of …

Recovery of iron values from the Barsua iron ore slimes containing 56% Fe, 4.8% SiO 2, 7.2% Al 2 O 3 and 7.0% LOI by the addition of synthetic colloidal magnetite and oleate colloidal coating followed by high gradient magnetic separation technique was investigated. The effects of concentration of colloidal magnetite, pH, and magnetic field strength were studied.

A dried iron ore slime sample with a Fe mass fraction of 56.2% was obtained from the slime pond of the Barsua mines, Western Odisha, India. The sample comprised of around 25% by weight of coarse particles of +500 μm while 46% of the samples reported below 45 μm.

Iron ore slime is a micro-fine of size below 20 µm in majority and rich in alumina and silica. It is neither suitable for pelletization nor sintering. Jhama coal is not also used in the iron making because of its poor caking property and thermal stability of lump.
