In the exteraction of copper from its sulphide ore, the metal is fanally obtained by the reduction of caprous oxide withA. copper (I) sulphide `(Cu_(2)S)`B. sulphur dioxide `(SO_(2))`C. iron sulphide (FeS)D. carbon monoxide (CO)

In the exteraction of copper from its sulphide ore, the metal is fanal

1.	In the exteraction of copper from its sulphide ore, the metal is fanally obtained by the reduction of caprous oxide withA. copper (I) sulphide `(Cu_(2)S)`B. sulphur dioxide `(SO_(2))`C. iron sulphide (FeS)D. carbon monoxide (CO)
Answer» Correct Answer - A In the extraction of copper from its sulphide ore, when ore is subjected to roasting, some of it is oxidised to `Cu_(2)O` which reacts with the remaining `Cu_(2)S` (sulphide ore) to give copper metal. `2Cu_(2)S + 3O_(2) rarr 2Cu_(2)O + 2SO_(2)uarr` `2Cu_(2)O + Cu_(2)S rarr 6Cu + SO_(2) uarr` In this process `Cu_(2)S` behaves as reducing agent.
