The most important copper oxide containing minerals are azurite `{Cu_(3)(OH)_(2)(CO_(3))_(2)}`, malachite `{Cu_(2)(OH)_(2)(CO_(3))}`, cuprite `(Cu_(2)O)`, tenorite `(CuO)`. Extraction of copper from these low grade ores involves leaching followed by reduction
Malachite `("leached")/("with bacteria") ("solution")`
`Cu` can be extracted from solution on treatment with:

Options

A. `Ag`
B. `FeO`
C. `H_(2)`
D. `H_(2)SO_(4)`

Answer

C

Explanation

` Cu^(+2)(aq.)+H_(2)rarrCu+2H^(+)`
