WhatsApp: +86 18203695377Introduction. Iron is one of the most common elements in Earth's crust. The primary industrial types of ironbearing minerals include oxides and hydroxides and, to a lesser extent, carbonates: magnetite [Fe 3 O 4], hematite [Fe 2 O 3], goethite [FeO(OH)], limonite [FeO(OH) × nH 2 O] and siderite [FeCO 3].The genesis of iron ore deposits is variable, similar to numerous other ore types.

WhatsApp: +86 18203695377Download. Iron (Fe) is a metallic element that constitutes % by weight of the Earth's crust and is the fourth most abundant element in the crust. Iron ores are rocks from which metallic iron can be economically extracted. The principal iron ores contain hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ). Hematite is an iron oxide mineral.
WhatsApp: +86 18203695377Steel is made from iron, which comes from iron ore, which is a combination of iron oxides (Fe x O y) and various mineral components. The current method for processing iron ore is by melting it in a blast furnace, causing the iron oxide to separate from the other parts of the ore. Hot oxygen interacts with coal in the furnace to create carbon ...
