Iron ore : definition of Iron ore and synonyms of Iron ore …

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 color 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).

 · First, it confirmed that grinding the ore finer resulted in improved magnetite liberation which led to improved iron and magnetite grades with the finer feed sizes. For example, with the average size of the magnetite mineral in the ore being approximately 26 µm, crushing the feed to P 80 = 30 µm resulted in higher magnetite liberation and hence, yielded the highest iron and magnetite grades.
