Smelting
Ramesh Singh, in Applied Welding Engineering (Second Edition), 2016. Smelting. Smelting is an energyintensive 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 .

Energy and materials flows in the copper industry
Most copper is extracted by smelting sulfide ores, with concomitant production of sulfur dioxide. Clean air regulations will require smelters to reduce sulfur emissions, necessitating smelting process modifiions that could also save 20 x 10/sup 12/ Btu (10 x 10/sup 6/ Btu/ton of copper) in smelting energy.
