How is leaching carried out in case of low grade copper ores? |
|
Answer» SOLUTION :The leaching of the low grade copper ores is carried out with ACIDS in presence of air when copper dissolves giving `Cu^(2+)` ions. Thus, `2CU(s)+2H_(2)SO_(4)(aq)+O_(2)(G) to 2CuSO_(4)(aq)+2H_(2)O(l)` or `Cu(s)+2H^(+)(aq)+(1)/(2)O_(2)(g) to Cu^(2+)(aq)+H_(2)O(l)`. |
