girishchandra, Ok, I'll try to help.  Could you supply more detail please?  Some questions include:  What is the concentration of CuNO3 and what ingredients are there beside the copper salt, in other words what is the composition of the solution?  What is the pH of the solution?  What volumes are you processing?  Most importantly, what kind of help do you need?  Is there a particular stage of the recovery you need help with, or are you looking for the whole process, beginning to end?  We can't do much with so little information.

In order to recover copper from you just raise PH of your solution to 6 there you will have almost 90% of copper precipitated
