the extraction of metals from iron ores

The extraction of iron from its ores is quite a technical process The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres

Extracting iron Iron and aluminium GCSE Chemistry

Iron is extracted from iron ore in a huge container called a blast furnace Iron ores such as haematite contain iron(III) oxide, Fe 2 O 3 The oxygen must be removed from the iron(III) oxide in

Extracting iron and copper Extracting and using metals

An ore is a rock that contains enough of a metal or a metal compound to make extracting the metal worthwhile Most metals are extracted from ores found in the Earth's crust

Extraction of Metals from Ores – Different Processes

The basic extraction of metals from ores has the following steps 1 Grinding and Crushing The bigger chunks of the ore extracted are crushed and ground in ball mills and crushers It helps to increase the surface area of the chunks for better chemical actions later In technical terms, it is called pulverization 2 Concentrating the Ore This step concentrates the ore by performing the

The extraction of iron in the blast furnace Diagram showing the carbon extraction of iron Raw Materials: Iron Ore (Haematite), Coke, Limestone and Air Explanation: Iron Ore, Coke and Limestone are mixed together and fed into the top of the blast furnace Hot air is blasted into the bottom of the blast furnace; Zone 1 Coke is used as the

Extraction of Iron from its ores, Iron dressing, Reduction

23/10/2018· 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

GCSE CHEMISTRY Extraction of Metals History Iron

Extraction of Metals History After the Bronze Age came the Iron Age People discovered that a high temperature coal fire could be used for the extraction of iron from iron ore The extraction of iron today is done in a blast furnace The Iron Age began in Asia and Africa in 1,100 BC and came to Britain in 500 BC In many ways, we are still in the Iron Age take a look around Metals

Extracting metals How are metals with different

An ore is a rock that contains enough of a metal or a metal compound to make extracting the metal worthwhile, eg either: low grade ores contain a small percentage of the metal or its compound

How can metal mining impact the environment? |

Although the character of waste rock varies with the type of ore, many waste rocks contain sulfide minerals associated with metals, such as lead, zinc, copper, silver, or cadmium An important sulfide mineral common in waste rock is pyrite, iron sulfide When pyrite is exposed to air and water, it undergoes a chemical reaction called “oxidation” The oxidation process produces acidic

Reduction of Metals (Extraction from Ore) ALevel

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 to obtain the metal The metal oxide loses oxygen
