I have completed all process and added SMB to precipitate gold .
Then also reaction took place and gold dust start precipitating in good quantity too as I have processed more than 1 kg mix ic chips.
But I put that solution for 5..6 hours and I went away for some work. And now when I am retuned to my place I am seeing that the solution is again yellow all precipitate gone into solution again. So wheta the problem here and what's the solution for this? Help needed.
