Blast furnace | metallurgy |

Blast furnace. The iron oxides in the ore are chemically reduced to molten iron by carbon and carbon monoxide from the coke. The slag formed consists of the limestone flux, ash from the coke, and substances formed by the reaction of impurities in the ore with the flux; it floats in a molten state on the top of the molten iron.

Difference Between Iron Ore and Iron | Compare the ...

Jun 14, 2011· Iron is extracted from its ore through removal of oxygen, which is a process called its reduction. Another process is through blast furnace where the ore is heated with carbon (coke). Iron thus produced using coke in blast furnaces is called pig iron, while iron produced through direct reduction is called sponge iron.

Managing Ore Loss and Dilution for Blast Optimisation

blast the ore blocks within the blast volume are fractured and moved for efficient loading and subsequent downstream comminution processes. A lack of understanding of ore block movements within a blast increases the risk of ore loss and dilution. JKTech, along with the University of Queensland's W H Bryan Research Centre (BRC)

Mine wastes management Mining and Blasting

Mine wastes management Mining wastes is generated during the process of extraction, beneficiation and processing of minerals. Extraction is the first phase that consists of the initial removal of ore from the earth. This is normally done by the process of blasting, which results in generation of large volume of waste (soil, debris and other material).

Corrosionpedia What is a Blast Furnace? Definition ...

Corrosionpedia explains Blast Furnace. The air blasts are produced at the bottom to boost the reactions aimed at reducing the iron ores into pure iron. The coke undergoes redox reactions to form carbon monoxide, which is necessary for the reduction of iron ores. The limestone is broken down into calcium oxide, which is used to remove sulfur form the ore.

From ore to steel – ArcelorMittal

Finegrained iron ore is processed into coarsegrained clumps for use in the blast furnace. Coal is cleaned of impurities in a coke furnace, yielding an almost pure form of carbon. A mixture of iron ore and coal is then heated in a blast furnace to produce molten iron, or pig iron, from which steel is made.

How it works: The Blast Furnace StokeonTrent

The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom. The raw materials require 6 to 8 hours to descend to the bottom of the furnace where they become the final product of liquid slag and liquid iron.
