Question

Why metals with high reactivity cannot be extracted from their oxides
from simple reduction?

Answer 1

Answer:

Metals such as zinc, iron and copper are present in ores as their oxides. Each of these oxides is heated with carbon to obtain the metal. The metal oxide loses oxygen, and is therefore reduced. ... Some metals, such as aluminium, are so reactive that their oxides cannot be reduced by carbon

Answer 2

BECAUSE THEY ARE MORE LIKELY TO REACT WITH OXYGEN THAN CARBON OR ANY OTHER REDUCING AGENT
