Collections: Iron, How Did They Make It? Part I, Mining

Iron ore, even crushed, is terribly heavy and bulk and as we'll see next week, the ratio of metal to useless rock really favors useless rock. Consequently, if you could do the entire smelting process at the mine, you did, rather than transport so much of that useless rock far away only to have it turned into slag there.

Iron Ore Smelting Process Bright Hub Engineering

Iron ore is obtained in the conventional method of open cast or underground mining and conveying the ore to the surface preparation are where it is crushed, washed, and transported to the smelter. Here the ore is put into a blast furnace along with limestone and coke and subjected to hot air blasting and heat which converts the ore to molten iron.

Iron: From mythical to mundane The Roots of Progress

The smelting of ore into cast iron had become relatively efficient, but the further refining took days or weeks—an enormous amount of fuel and labor. That was about to change. A worker turns and stirs the iron with a pole in the puddling process Wikimedia

Slag analyses from archaeological iron smelting sites are common. Rigorous analyses of iron and slag from successful experimental smelting, however, are still rare. Furthermore, thorough analyses from a series of smelts, and of the slag produced in different phases of the smelt, are exceedingly rare. The present study investigates the effect of an iron smelter's decisionmaking and skills on ...

Steelmaking Wikipedia

Steelmaking Wikipedia

Steelmaking. Steelmaking is the process of producing steel from iron ore and/or scrap. In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (the most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce ...

In Corex process, a large amounts of iron ore fines (−8 mm) and coal fines (−6 mm) remain unutilized, causing difficulties. Thus, FINEX process is a fine orebased smelting reduction process. It is a technology combining a gasbased reduction in a series of fluidized bed reactors and a reduction smelting in a melter gasifier.

The cost of highpurity iron produced by this process is shown in Table 6. It is a rough estimate, based on a project design we have done previously. In fact, the data in Table 6 are a magnified result, while the actual cost should be lower. The iron ore grade is calculated as 60% TFe. If one tonne of iron is produced, tonnes of ore is ...

What we see is that the various iron oxides are turned into iron in several steps, always producing FeO or wüstite first. The first two reactions (roasting) you can do separately from smelting, you sort of condition your ore. Reduction of the wüstite is the final reaction in the smelter, it produces the elemental iron.

The Hismelt process employs a single smelt reduction vessel (SRV) where iron oxide fines are injected deep into hot metal melt, which instantly reduces the ore to produce iron and carbon monoxide. Flux and coal are also injected into the bath near the bottom, which enables carbon replenishment and captures impurities (silica, etc.).
