Issues relating to quality control in iron ore production are discussed in 12. When ore is crushed and split into lump and fines components there are systematic differences between the lump and fines compositions. The lump component is usually but not always richer in iron and with less silica and alumina than the fines product.

The results of this study demonstrated that low-grade iron ore fines can be upgraded by means of STET tribo-electrostatic belt separator. Further work at the pilot plant scale is recommended to determine the iron concentrate grade and recovery that can be achieved. Based on experience the product recovery andor grade will significantly .
Lump and fines ratios in Indian iron ore deposits are almost 5050 as shown in . Figure 1 but only 12.3 of these reserves belong to high grade category while 48 belong to medium grade 26 to low grade and rest to unclassified categories 5. Iron ore range in size from less than 8 mm to 0.15 mm are designated as fines whereas
Jul 09 2015 In the present investigation magnetic separation studies using an induced roll magnetic separator were conducted to beneficiate low-grade ferruginous manganese ore.

Description. Iron Ore fines Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey bright yellow deep purple to rusty red. The iron itself is usually found in the form of magnetite Fe 3 O 4 hematite Fe 2 O 3 goethite FeOOH limonite FeOOH.nH 2 O or siderite FeCO 3.

Low-grade ore is a term applied to iron-rich rocks with cut-off grades in the range of 25 30 Fe. It was the main supply of iron ore for many centuries of the Worlds early history of production of iron. Since the 1950s North Americas main supply has been low-grade ore. The dominant economic iron mineral in low-grade ore is magnetite.
