Typical harmful minerals in iron ore include pyrite and apatite, which contain the harmful elements S and P. They are also weakly magnetic. But if their magnetic susceptibilities are smaller than for oxidized iron ores, it is still possible to partially remove them from oxidized iron ores by magnetic separation.

Iron ore - Wikipedia

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, or deep purple to rusty red. The iron is usually found in the form of magnetite, hematite, goethite, limonite or siderite. Ores containing very high quantities of hematite or magnetite are known as "natural ore" or "direct shipping ore", meaning .

How is Iron Refined from Ore? (with pictures) - wisegeek

Jul 29, 2019 · Iron ore consists of oxygen and iron atoms bonded together into molecules. To create pure iron, one must deoxygenate the ore, leaving only iron atoms behind, which is the essence of the refining process. To coax the oxygen atoms away from the ore requires heat and an alternate atomic partner for the oxygen to bond to.
