Can someone tell me ?

[cerise]

I wanted to know what to do next?
I have 850 grams of fingers in AP (2500 ml of HCL and 1250 of H2O2)
I know how to get the flake out of It
But what I dont know is ,how to preciptate the gold out of the AP after the flake is out.Does SMB work and how much SMB do i put in the solution.Also does this SMB precipitate just the gold out ? If not does amonia Hydroxide pull the copper out ?O yea where do i get SMB ?
Thanks
Cerise.
P.S.
Have a safe 4th and remember guys ,He who accepts Security for Liberty deserves neither.June 20th Your boys in office were trading our liberty for Just that HR 6304 - A Bill to Abolish the 4th Amendment.http://www.youtube.com/watch?v=MIJdmePn4lY


I know this is a forum for Refining but I Thought it being apropriate for our National Day of INDEPENDENCE.

Cerise,

SMB is available from http://chemistrystore.com

Don't worry about the little bit of gold dissolved in the AP, most of your gold is in the foils. What's in the AP will come out in time as you resuse the solution on your next batch. As the copper level in the AP gets higher the gold will be forced out as fine black powder. It will come out in the filter with the foils then.

Thank-you Steve.
When should I add more HCl and H2o2 ,Should i keep them in 1:2 ratio when adding more because of evaporation?
