Kiruna Iron Ore Mine Mining Technology Mining News

With an ore body 4km long, 80m thick and reaching a depth of 2km, LKAB's Kiruna is the world's largest, most modern underground iron ore mine. Since mining began at the site over 100 years ago, Luossavaara-Kiirunavaara AB (LKAB) has produced over 950Mt of ore, yet only one third of the original ore body has been extracted.

Iron Ore Smelting Process Brighthub Engineering

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 being
