Iron Ore Smelting Process
The ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron. The slag and molten iron are tapped off from the bottom of the furnace, the slag …
BHP to pilot green smelting furnace using electricity, …
Australia is a big player in steel: it produces around 3.5 million tonnes of steel annually and, more importantly, exports up to 900 million tonnes of iron ore per year to be smelted into steel ...
Environmental and Economic Aspects of Charcoal Use in …
iron ore fines are either sintered or pelletised and then fed into the blast furnace along with iron ore lump. Coke, pro-duced from coal in the coke ovens, is used as a fuel and re-ductant in the blast furnace together with fluxes to produce pig iron. Natural gas is also commonly used as a supple-mentary fuel in the blast furnace.
Guide to Modern Smelting Processes
Guide to Modern Smelting Processes – T09-002 5 Iron Smelting: Iron smelting involves reducing iron ore, typically hematite or magnetite, in a furnace. The high temperatures required (over 1500°C) posed significant challenges. Early iron smelting was accomplished using charcoal- fueled furnaces known as bloomeries.
The Role of Coke in Steel Making Process
Coke is crucial in steel production, providing heat and chemical reactions for smelting iron ore while also structuring the blast furnace. However, its use emits pollutants and CO2, contributing to environmental concerns. Useful tips on the subject:
DF2014:Smelting
Smelting is the act of refining raw stone ore(s) into useful bars of pure metal(s) or alloys. Smelting is similar but distinct from melting, which reclaims existing metal objects back into (fractional) bars.Metal bars produced at a smelter are usable in a wide variety of goods, from weapons, to goblets, to furniture, to buildings.. Smelting also refines bituminous coal or lignite into coke, a ...
