Ramesh Singh, in Applied Welding Engineering (Second Edition), 2016. Smelting. Smelting is an energy-intensive process used to refine an ore into usable metal. Most ore deposits contain metals in the reacted or combined form. Magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite (αFeO[OH]), limonite (the generic formula for limonite is FeO[OH].nH 2 O), and siderite (FeCO 3) are iron ores, and ...

Under certain circumstances surface mining can become prohibitively expensive and underground mining may be considered. A major factor in the decision to operate by underground mining rather than surface mining is the strip ratio, or the number of units of waste material in a surface mine that must be removed in order to extract one unit of ore.

Iron Geoscience Australia

2021-11-18  Iron is the backbone of the world we have built around us and it is the basic ingredient of steel (iron plus carbon). Iron is a very useful metal because it can be mixed with other metals to make a whole variety of 'alloys' which are even stronger and don't rust easily and can be shaped into products from cars to pins, household appliances to buildings, bridges to railways, food cans to tools.

Coke is put into a blast furnace with iron ore; they are melt-ed at high temperatures and they chemically react. Through such processes, iron oxide contained in the iron ore is reduced by coke and it turns to iron containing carbon of slightly less than 5% (pig iron).
