Why is it important to recycle metals that you extract by electrolysis?

It takes a lot of electric power to refine metals by electrolysis. Such metals therefore are a kind of stored energy. If they are not recycled, that energy is lost, and more energy will be needed to refine more metals by electrolysis to replace them. High energy consumption is a major factor in environmental pollution.

Why is it important to recycle the metals you extract using electrolysis?

Why is electrolysis used to extract certain metals?
Electrolysis can be used for the following purposes:Electroplating a baser metal with a more attractive metal. e.g. electroplating brass with goldRefining of impure metals. e.g. to remove impurities from copperElectrometallurgy - to extract metals from their compounds
Which common way of extracting metals is the most expensive?
it is to extract the metal by electrolysis
What is the methord to extract reactive metals fom their compoundsby passing a current through them?
This process is known as electrolysis.
Why are aluminium and titanium expensive to extract?
They are reactive metals, and so need to be extracted from their ores using electricity, whereas less reactive metals like iron can be extracted by smelting - roasting with carbon - which is a lot cheaper to do. Both metals are useful because they both do not corrode, as they both have an oxide layer to protect them from corrosion. They both need to be extracted by a process called "electrolysis" which means to break up substances using electricity. Electrolysis uses a lot of energy (ie- very high temperatures) and a great deal of electricity. Therefore we need to recycle aluminium to conserve energy, as recycling aluminium does not require electrolysis.
How will you determine the purity of some metals?
use electrolysis
Why is it important to recylce metals?
It is important to recycle metals because all the resources on earth is limited and no one on earth would like to run out of resources. Recycling is much economic than digging up metals in their compound form and then extracting it.
How do you avoid running out of metals?
Recycle
How can you conserved metal ores?
you can recycle the metals or use alternative metals.
The process of electrolysis used to coat objects with metals is?
galvanisation
Name the metals extracted by electrolysis?
aluminium bromide lead
How many ways of making metals?
by electrolysis by thermal reduction
