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 color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO ...

14-6-2011 · Iron ores make up nearly 5% of the earth’s crust, and when we consider both the crust as well as inner core, iron and its ores make up about 35% of the mass of the earth. Iron is extracted from its ore through removal of oxygen, which is a process called its reduction.
Iron ore mining and dressing - tec-science
Iron does not occur in nature as a pure substance but as a compound in rocks, which can contain up to 50 % iron. These ferrous rocks are also called iron ores. The iron compounds contained therein are mainly iron oxides, but also iron carbonates or iron sulphides. The most important iron oxides include: magnetite: \(Fe_3O_4\)
Slag - Wikipedia
Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore.Slag is usually a mixture of metal oxides and silicon dioxide.However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control of ...
