Lately I have been wondering if I have been evaporating stuff and not really needing to. I have mostly been working with HCl/Cl process and the other day I decided to try to incinerate some filter papers that I had just to see, that went OK besides all the rookie mistakes on that but when I finally got all the ash and stuff in the HCl/Cl and filtered I had like 300ml of light yellow solution which showed a faint positive test. So I decided to evaporate it with just slight heat, got it down to about 50 ml all the while testing the vapor periodically for gold, which as far as I could tell were negative. Question one , at this point is this the solution I need to dilute 3x before smb? Question two do I really need to do this (I guess not) other than reducing the volume and losing some gold in the vapors that I would imagine would be so slight I might not see a test but after 200ml leaving might add up. I know it is good to remove excess Cl and SO2 from various stages of the processes but really am I just adding hours to a process that I don’t need to.. Just some thoughts
