Mining of Iron Ores IspatGuru

Mining techniques usually consist of two types based on excavation methods. These are surface mining and underground mining (sub surface mining). Iron ore is almost exclusively mined by surface operations. The most predominant surface mining methods used for mining of iron ores are open pit mining methods and open cut mining methods. However a few underground iron ore mines are also

Hurstwic: Iron Production in the Viking Age

Although Norse people knew of mining and mined some iron ore in a variety of locations throughout Scandinavia, most Viking era iron was smelted from bog iron. The photo to the left shows the bog at Rauðanes in Iceland, where Skallagrímur Kveldúlfsson, one of the early settlers in Iceland, had his smithy. Chapter 30 of Egils saga describes him as a "great smith" who "smelted a lot of bog

Refining (metallurgy) Wikipedia

In metallurgy, refining consists of purifying an impure metal. It is to be distinguished from other processes such as smelting and calcining in that those two involve a chemical change to the raw material, whereas in refining, the final material is usually identical chemically to the original one, only it is purer. The processes used are of many types, including pyrometallurgical and

Mining Wikipedia

The mining industry in the early Middle Ages was mainly focused on the extraction of copper and iron. Other precious metals were also used, mainly for gilding or coinage. Initially, many metals were obtained through open-pit mining, and ore was primarily extracted from shallow depths, rather than through deep mine shafts. Around the 14th century, the growing use of weapons, armour, stirrups
