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 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, limonite or siderite.Hematite is also known as "natural ore".

Iron Separation from Iron-Rich Manganese Ore Leachate
In the current electrolytic manganese industry, iron separation and reuse from iron-rich manganese ore leachate (IRMOL) has become one of the most pressing challenges. This study aimed to investigate the optimal conditions for iron separation from IRMOL and to assess the economic and practical advan …
Developments in the physiochemical separation of iron ore
The principal separation in iron ore beneficiation, therefore, is between the iron minerals, hematite and/or magnetite, and silica, principally in the form of quartz. The use of flotation, either alone or in combination with magnetic separation, has been well established as an efficient method for rejecting silica from these iron ores. ...
Extraction of Iron: Meaning, Purification,
Iron is extracted from its ore (haematite, Fe₂O₃) in a blast furnace. The ore is mixed with limestone (CaCO₃) and coke (a form of carbon) and heated to very high temperatures. Coke burns to produce heat and reduces the iron …
