Question

Chemistry Question on Concentration of ores

In the extraction of Cu, the metal is formed in the bessemer converter due to the reaction:

A

\ceCu2S+2Cu2O>6Cu+SO2\ce{Cu2S + 2Cu2O -> 6Cu + SO2 }

B

\ceCu2S>2Cu+S\ce{Cu2S -> 2Cu + S }

C

\ceFe+Cu2O>2Cu+FeO\ce{Fe + Cu2O -> 2Cu + FeO }

D

\ce2Cu2O>4Cu+O2\ce{2Cu2O -> 4Cu + O2 }

Answer

\ce2Cu2O>4Cu+O2\ce{2Cu2O -> 4Cu + O2 }

Explanation

Solution

Decomposition of carbonates and hydrated oxides.
