Greetings All,
This is my first post. I like to find the answer for my self but this one has me stumped. I am sure the answer is staring me in the face but I can see it. :shock: I am hoping someone may have some insight into my problem.
I began with 53 grams of call phone pins and other nick knacks found in there. I put these into AP ( a 50/50 solution of HCL and Peroxide) for a good while (4 hrs). I know this may not have been long enough but I needed to move and I hoped that I got most of the base metals as the solution was a very dark green. I filtered this solution through 4 coffee filters. After filtration I added the black powder and foils into a clean beaker with the nick knacks which still had gold foil on them. To these things I added about 100 to 150ml of HCL and 1 teaspoon of sodium nitrate (shor product). I waited about 1 hr and checked that all was digested then filtered this solution again to a new and clean beaker. At this point, I added 28grs of SMB which I dissolved in 240ml of water to the solution and stirred. I waited for some sort of reaction but none was forthcoming so I heated it again and added 1 and 1/2 tablespoons of the Shor storm precipitate in the hopes that something would happen. Again, nothing. I added a little "picker" gold I had to check for free nitric. I did not notice any reaction.
This morning the solution was a deep golden color with no precipitate. I wet a Q-tip with Ammonia and held it over the beaker which immediately reacted.
My questions are these:
What can I do to get this thing to drop?
Is there a post which deals with this problem? If so, could someone post a link?
If the answer is in Ms. Hoke's book could someone tell me the chapter? I did not see any mention except the evap which I am trying now.
I appreciate any help and/or constructive criticism on how I might improve. Below is a photo of what I am dealing with. I hope I attached it right. I am sorry if I multi posted that was not my intent.
Sincerely,
Patrick
