Question

Why do we extract metals? Answer within 70 words...

Answer 1

The method used to extract metals from the ore in which they are found depends on their reactivity. For example, reactive metals such as aluminium are extracted by electrolysis, while a less-reactive metal such as iron may be extracted by reduction with carbon or carbon monoxide.

Answer 2

Metals are extracted from their ores. Generally tge metals which are at the top of the reactivity series are directly obtained in form of oxides by electrolysis and tgen oxidation of their oxides
Metals which are moderately reactive are rither in carbonate ores aur sulphide ores
Carbonate ores go through calcination and then oxidation.
Sulphide ores go through roasting and then oxidation for extraction of pure metals
Metals at the end of reactivity series and generally in sulphide ores so we do the roasting and oxidation


There you go bud
