Extraction method is from the metal oxide for Carbon and Hydrogen, and the metal carbonate for Heating. Refer to TB for details on the reactions of metals. Note:- Metals above hydrogen will react with dilute acids to produce hydrogen gas (they are more reactive and hence can displace hydrogen from solutions of acids).

The Extraction of Metals •The lower the position of a metal in the reactivity series, the easier it is to extract. The reactivity series and the method of extracting metals 9. Extraction of the Least Reactive Metals • The least reactive metals are at the bottom of the reactivity series. Some are found as free metals.
4.6 Recall that the extraction of metals involves reduction of ores; 4.7a Explain why the method used to extract a metal from its ore is related to its position in the reactivity series and the cost of the extraction process, illustrated by: heating with carbon (including iron) Edexcel Combined science. Topic 4 – Extracting metals and equilibria
During metal extraction, the bulk of the metal is separated from the impurities present in the ore by using a system which invariably comprises more than one phase. The metal enters the metallic phase while the impurities enter the non metallic phase or phases. The driving force for the reactions
It has been shown to provide high (>95 per cent) and selective extraction efficiencies for the key valuable metals, i.e. Pt, Pd, Rh, Au, Ni, Co, and Cu. The Kell Process consists of several
Metals that are higher than zinc in the electrochemical series are extracted using electrolysis. These very reactive metals cannot be extracted by other metals such as reduction with carbon. The reactive metals are obtained by electrolyzing a molten ionic compound of metal. Case Study: Extraction Of Aluminium

How are metals extracted from mineral ores? How do we make iron, steel, other alloys, aluminium, sodium, copper, zinc, titanium and chromium. The six linked pages include an introduction to metal extraction or metal manufacture and production. There are detailed notes on the extraction of iron and its conversion to steel.
EXTRACTION OF IRON IN A BLAST FURNACE Iron is also below carbon in the reactivity series, so therefore carbon can be used to reduce it (note: reduction can also mean to remove the oxygen from a compound). This is done in a blast furnace.
10 Science Occurrence and Extraction of Metals. Source of metal: Metals occur in earth’s crust and in sea water; in the form of ores. Earth’s crust is the major source of metal. Sea water contains many salts; such as sodium chloride, magnesium chloride, etc.

Extraction of Metals. The ease of obtaining metals from their ores depends on the metals position in the reactivity series. An ore is a mixture of mineral containing a metal compound within it.
