Answer:
Extraction of aluminium
It is expensive, largely because of the amount of electricity required in the extraction process. ... The ions in the aluminium oxide must be free to move so that electricity can pass through it. Aluminium oxide has a very high melting point (over 2000°C) so it would be expensive to melt it.Aluminium extraction is expensive because the process needs a lot of electrical energy. Titanium extraction is expensive because the process involves several stages and a lot of energy. ... Aluminium and Titanium both have a low density which means they are lightweight for their size. Metals of high reactivity; such as sodium, calcium, magnesium, aluminium, etc. are extracted from their ores by electrolytic reduction. These metals cannot be reduced using carbon because carbon is less reactive than them. ... Metal; being positively charged; is deposited over the cathode. please mark it as brainliest answer and follow me please please please please
