# Write Chemical Reactions Taking Place in the Extraction of Copper from Cu2 S. - Chemistry

#### Question

Write chemical reactions taking place in the extraction of copper from Cu2 S.

#### Solution

The sulphide ores are roasted to give oxides

$\ce{2Cu2S + 3O2 -> 2Cu2O + 2SO2}$

The oxide can easily be reduced to metallic copper using coke

$\ce{Cu2O + C -> 2Cu + CO}$
