5 1 explain how the methods of extraction of the metals in this section are related to their positions in the reactivity series Metal Way of extraction potassium sodium calcium magnesium aluminium extract by electrolysis carbon zinc iron tin lead extract by reaction with carbon or carbon monoxide hydrogen copper silver gold platinum extracted by various

The Iron Age began in Asia and Africa in 1,100 B C and came to Britain in 500 B C In many ways, we are still in the Iron Age take a look around Metals above carbon in the reactivity series can only be extracted by electrolysis The discovery of electricity at the beginning of the nineteenth century allowed the extraction of the more

Extraction of Metals What is Electrolysis? Electrolysis is the process where an electric current is passed through a liquid that conducts electricity A liquid will only conduct electricity if it contains ions The electrodes are often made from graphite The liquid that conducts electricity is called the electrolyte The amount of electricity needed to produce a

When the metal is dug up, a method must be used to separate the metal from the rest of the ore This is called extracting the metal The method of extraction depends on how reactive the metal is The more reactive the metal, the more difficult it is to extract from its compound Electrolysis Electrolysis is the most powerful extraction method

THE EXTRACTION OF METALS AN INTRODUCTION 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 aluminium, copper, iron and titanium are given

May 09, 2017 How is electrolysis used in the industry?

How is aluminum extracted using electrolysis please, can you help mate ? Help me I really need help for my class work I really need a lot of help Aluminum is extracted from aluminum oxide by a process called electrolysis First of all, aluminum oxide needs to be in molten form to extract the aluminum ions

Electrolysis, or electrolytic refining, is a technique used for extraction, as well as purification, of metals obtained by any refining method In the electro refining process, a block of impure metal becomes the anode, and a thin sheet of metal becomes the cathode Both the cathode and anode are

Extracting a metal by heating with carbon is cheaper than using electrolysis Question In the reaction of ironIII oxide with carbon, state which substance is reduced and which substance is

Oct 09, 2017 It simply means purifying the metal according to reactivity series CARBON is used to reduce oxides of metals below it in the reactivity series E g,oxides of zinc,lead, and iron can be reduced by carbon The carbon is usually used in the form of c
