Patterns of trace elements participating in PM 2.5 (aerosol dynamic diameter ≤2.5 μm) formation during iron ore sintering process were investigated. For elucidating this property, PM 2.5 collected from before and after the flue-gas-temperature-rising point (stage-1 and stage-2) was examined. The results show that trace elements including Pb, K, Na, Cl and S presented …

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".
