The process of mining consists of discovery of an iron ore deposit through extraction of iron ore and finally to returning the land to its natural state. It consists of several distinct steps. The first is discovery of the iron ore deposit which is carried out through prospecting or exploration to find and then define the extent, location and value of the ore body. This leads to a mathematical ...
The process of extracting metal ores buried deep underground is called Mining. The metal ores are found in the earth''s crust in varying abundance. The extraction of metals from ores is what allows us to use the minerals in the ground! The ores are very different from the finished metals that we see in buildings and bridges. Ores consist of the desired metal compound and the impurities and ...
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 ...
The extraction of iron from its ore is a long and subdued process, that helps in separating the useful components from the waste materials such as slag. What happens in the Blast Furnace?

Redox reactions are involved in the extraction of metals from their ores, eg extracting iron by reduction within the blast furnace. Transition metals have high melting points and densities, form ...
· Extraction of Iron from its ores. Extraction of iron or its metallurgy is the process of obtaining this metal in a form where it can be put to practical use, and this process of extraction consists of three stages: Ore dressing, Reduction of ores and Iron production. Extraction of Iron from its ores . The ore dressing. The aim of ore dressing is increasing the concentration of iron in the ore ...
This iron can also be used in steel production or purified further to give wrought iron. Waste gas mixture that exudes from the furnace contains majorly nitrogen, 30% carbon(II)oxide and about 10% carbon(IV)oxide. These waste gas mixture is used in preheating the air blast and the iron ore at the initial stages of the extraction process.
ZIMSEC O Level Combined Science Notes: Extraction of iron: The blast furnace. After iron ore is mined it is send to the blast furnace; Iron is extracted from its ore in a blast furnace . The structure of a blast furnace. Image credit The oxide ores are reduced to iron by removing the oxygen from them ; Coke, limestone and iron ore are fed into the top of the furnace; Hot air is ...
Iron Extraction Process. In the blast furnace process, the first step on the way towards heavy plate, pig iron is produced from iron ore. The composition of the ore and additions is accurately adjusted to the final products of AG der Dillinger Hüttenwerke and Saarstl AG. Burdening. Exact quantities of burdening materials such as sinter, pellets, lump ore, alloys, and coke are transported ...
Extracting iron from iron ore using a Blast Furnace. Introduction. The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke. Coke is produced by heating coal in the absence of air. Coke is cheap and provides both the reducing agent for the reaction and also the heat source as you will see below. Iron ores. The most ...
The following diagram shows how iron is extracted from iron ore in a blast furnace. Scroll down the page for more explanations on extraction of iron. Extraction of iron Very unreactive metals are found directly in the ground as elements, eg. gold. Most metals are found in ores .
Jan, extraction operation of iron ore in the studied mines are done by opencast mining extraction stages include drilling operations, blasting, loading and hauling hole drilling is done by rotary and percussion machinery in different diameter, and mm Optimized design of drilling and blasting operations in

· Ironmaking, the first step in making steel, involves the raw inputs of iron ore, coke, and lime being melted in a blast furnace. The resulting molten iron—also referred to as hot metal—still contains % carbon and other impurities that make it brittle. Primary steelmaking has two methods: BOS (Basic Oxygen Furnace) and the more modern EAF (Electric Arc Furnace) methods. The BOS .
stages involved in extraction of iron ore. stages involved in extraction of iron ore. The Extraction of Iron Chemistry LibreTexts. Nov 29, 2015 Extracting iron from iron ore using a Blast Furnace . a brief idea of the sort of environmental issues involved with the extraction of iron and its conversion to steel.
Iron processing, use of a smelting process to turn the ore into a form from which products can be in this article also is a discussion of the mining of iron and of its preparation for smelting. Iron (Fe) is a relatively dense metal with a silvery white appearance and distinctive magnetic properties. It constitutes 5 percent by weight of the Earth''s crust, and it is the ...
The increasing demand of iron ore at home and abroad further stimulates the development of the benefication of iron ore. As one of the leading enterprises in domestic mineral processing industry, Xinhai has been dedicated commitment to the research and development of iron extraction process and equipment for more than 20 years. According to the magnetic difference of different iron ore,

Explain the stages involved in the extraction of cast iron. Ans. The stages in the extraction of cast iron from its ore are as under. 1. Washing: In this method the crushed and finely powdered iron one is washed with stream of water to remove lighter gangue particles. When the lighter gangue particles are washed away and the heavier mineral ore settle down to the bottom. 2. Magnetic ...
In this machine the raw ore, after calcination was fed onto a moving belt which passed underneath two pairs of electromagnets under which further belts ran at right angles to the feed belt. The first pair of electromagnets was weakly magnetised and served to draw off any iron ore present. The second pair were strongly magnetised and attracted the wolframite, which is weakly magnetic. These ...
