How is leaching carried out in case of low grade copper ores?

A

Leaching is carried out with NaOH and `O_(2)`

B

Leaching is carried out with NaCN.

C

Leaching is carried out with acids in presence of `H_(2)`.

D

Leaching is carried out by boiling the ore with water.

Text Solution

Verified by Experts

The correct Answer is:
C
Leaching of low grade copper ores is carried out with acid or bacteria , when copper goes into solution as `Cu^(2+)` ions.
`Cu_((aq))^(2+) + H_(2(g)) to Cu_((s)) + 2H_((aq))^(+)`
