Question

what is the chemical use of carbon in copper extraction?
please answer for this question ⁉️​

Answer 1

$\texttt{\text{\large{{Solution}:}}}$

• This method of extraction works because carbon is more reactive than iron, so it can displace iron from iron compounds. Extracting a metal by heating with carbon is cheaper than using electrolysis. In the reaction of iron(III) oxide with carbon, state which substance is reduced and which substance is oxidised.

$\texttt{\text{\large{{Need to know}:}}}$

1. The Self-reduction process is used in the extraction of copper and lead.

• Self-reduction is a reaction in which no external reducing agent is required. It is called self-reducing because copper oxide itself reduced the copper sulfide to give copper and sulfur dioxide.
