The pure form of mineral from which a metal can be extracted is called the ore. Types of Ores. Given below are the types of ores with their examples- Oxide Ores- In this particular ore, the metals are present in the oxidised form. Obtaining metals from this ore is much easier. For example, Haematite ore ( Iron) and Bauxite ore (Aluminium)
In many cases the ore is an ... The extraction method depends on the position of a metal in the reactivity series. Exam Tip. Make sure you can explain why aluminium is extracted by electrolysis while iron is extracted by reduction as it is a question that often comes up.

Iron is extracted in a large container called a blast furnace from its ore, hematite Modern blast furnaces produce approximately 10,000 tonnes of iron per day The blast furnace. Diagram showing the carbon extraction of iron
Nickel processing - Extraction, Refining, Alloying: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating …
Cast iron. The molten iron from the bottom of the furnace can be used as cast iron. Cast iron is very runny when it is molten and doesn't shrink much when it solidifies. It is therefore ideal for making castings - hence its name. However, it is very impure, containing about 4% of carbon. This carbon makes it very hard, but also very brittle.
This page looks at the various factors which influence the choice of method for extracting metals from their ores, including reduction by carbon, reduction by a reactive metal (like sodium or magnesium), and by electrolysis. Details for the extraction of …
Iron processing, use of a smelting process to turn the ore into a form from which products can be fashioned. Included in this article also is a discussion of the mining of iron and of its preparation for smelting.
Extractive metallurgy is the practice of removing valuable metals from an ore and refining the extracted raw metals into purer form. The field of extractive metallurgy encompasses many specialty sub-disciplines, including mineral processing, …
This method of extraction works because carbon is more reactive than iron, so it can displace close displace Take the place of another substance in a chemical reaction. For example, a metal can ...

The two methods used for extracting sodium metals are, ... NaOH) is electrolyzed using an iron cathode and nickel anode. A nickel wire gauze cylinder prevents the electrodes from touching each other. ... How the sodium metal is extracted from its salt NACL to extract the sodium from its ore on which solvent does AIDS salt will be dissolved ...
Extracting copper from its ores. The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ((CuFeS_2)) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest …
Iron can be extracted from its ore using carbon, which is great. Carbon is very cheap and very available. The carbon used to extract iron is commonly obtained from coal. Coal often contains hydrocarbons and other volatile impurities. Heating coal to over 1000 degrees Celsius will drive off some of these impurities, forming something we call coke.
Discuss the method of extraction of iron from its ore with the help of equations and diagram. Also discuss the thermodynamic principle of the reduction of its oxide into metal. Discuss the method of extraction of iron from its ore with the help of equations and diagram. Also discuss the thermodynamic principle of the reduction of its oxide into ...
