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 (FeO(OH)), limonite (FeO(OH).n(H 2 O)) or siderite (FeCO 3).

lump ore proportion increasing was discussed. All of these ... is found that the difference of iron grade and gangue con-tent is not large, while the S and P content of the imported ... was screened with the standard screen, and the percentage of the sample with the particle size less than 6.3mm was taken as the DI. (3) Softening Properties
High-phosphorus oolitic iron ore, treated by suspended flash magnetic roasting, contained 42.73% iron (mainly present as magnetite) and 0.93% phosphorus (present as collophane). Low-intensity magnetic separation (LIMS) was combined with reverse flotation to increase the iron and reduce the phosphorus contents of the roasted product. The results showed that an optimized iron ore concentrate ...
High grade concentrates and high recovery of iron ore can be achieved using effective feed preparation systems (typically controlled crushing, screening, milling, classification and slimes removal) in combination with cost effective, efficient metallurgical separation. Hard rock hematite deposits often require a combination of milling ...
The increased exploitation of low grade iron ore deposits containing magnetite has lead to an increased demand for complex beneficiation circuits.
