This method can be used to extract iron because carbon is above iron in the reactivity series and can therefore displace the iron from iron oxide. This process is completed inside a blast furnace where the high temperatures created provide the energy needed to melt the ore and break the ionic bonds holding the iron(III) oxide together.

This page looks at the use of the Blast Furnace in the extraction of iron from iron ore, and the conversion of the raw iron from the furnace into various kinds of steel. Contributors and Attributions. Jim Clark (Chemguide.co.uk) Prof. Robert J. Lancashire (The Department of Chemistry, University of the West Indies)

Iron is found naturally in the form of ores that are oxides of the pure metal, such as hematite and magnetite. The most common of the modern methods used to extract iron from its ores is coke smelting in a blast furnace.

A typical surface mine can produce up to 150,000 tons of ore every day. Sometimes whole mountains (or tops of mountains) are removed through surface mining processes. The most predominant surface mining methods used to extract iron ore are open-pit and open-cut methods. These two methods are considered to be the least expensive …

Magnetite Ore Processing Plant. The beneficiation process of magnetite mainly includes 4 stages. Once you have discovered or mined magnetite, you can extract iron concentrates through the following process.

The cast iron is usually extracted from its oxide ore (haematite). This process involves the following steps: The ore is crushed in jaw crushers and is broken to small pieces of about 1 inch in size. The crushed ore is concentrated …

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.

There are 3 main methods of extracting metals from their ore. They are reduction of the ore with carbon, reduction of the molten ore by electrolysis, and reduction of the ore with a more reactive metal. Extraction using carbon. Metals such as zinc, iron and copper are present in ores as their oxides. Each of these oxides is heated with carbon ...
