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

1.	How is leaching carried out in the case of low grade copper ores?
Answer» In case of low grade of copper, hydrometallurgy technuque is used extraction . Here leaching process can be done by using acids (or) bacteria. The solution cantainig` Cu^(+2)` is treated with scrap iron (or) `H_(2)`. `Cu_((aq))^(2+)+H_(2_((g)))rarrCu_((S))+2H_((aq))^(+)`

The Value of `DeltaG^(@)` for the formation of `Cr_(2)O_(3)` is `-"540KJ mol"^(-1)` and that of `Al_(2)O_(3)` is `-827"KJ mol"^(-1)`. Is the reduction of `Cr_(2)O_(3)` possible with Al ?
The reaction, `Cr_(2)O_(3)+2AlrarrAl_(2)O_(3)+2Cr(DeltaG^(Theta)=-421KJ)` is the thermodynamically feasible as is apparent from the Gibbs energy value . Why does it not take place at rom temperture?
