OK let me explain, I made AR the right method, HCL 1st the added nitric little by little until everything is dissolved and I keep it at 80c. Also I had a couple of filters in with the gold. It was getting late so I turn off the heat and let the solution cool overnight and went back to it after work. I looked at the solution and it was a dark brown with the filters on the bottom disintegrated, I mix the solution and realized there was gold flakes still undissolved, the solution was dark brown and opaque with lots of small gold specks though it. so I did this.
1. I Tried to get rid of the filter material with a metal strainer, but realized that I could not do it cuz it was catching too much of the gold solution
2. Rinsed the strainer with water and clean it so all material is back in the solution
3. I had a lot of solution so I boiled it to concentrated a bit
4. Added fresh HCL 200 ml
5. Added Nitric Little by Little, like 50 ml
At this point some of the gold specs where not gone all the way, so what did I do? I kept adding nitric (embarrassed in how much like 25-30ml) 5ml at a time, and still not all sparkly stuff would not dissolved. then I added more fresh HCL about 200ml and more nitric (another 25-50ml, 5ml at a time). Long story made short I had too much Nitric and still sparkly stuff, so I decide to filter and drop the gold
So I put a tiny amount of smb to drop the gold and it was like a grade school science fair project, ya know the one with the volcano and baking soda with vingar. Thank goodness I was being carful and only put a little smb. Ok, with all that being said I know I made lots of mistakes with this one, but this was not my 1st extraction and purification. So that being said, I know uera is for my garden and should stay the heck away from my gold extraction lab but it was late and I was desperate and I did have it around for my garden, I have never had to use it before because I always have been careful about how much HN03 I used. So I used urea
and in order to get rid of all NH03 and I had to use alot of it
. Finally the smb didnt fizz so much so I was able to use it to drop my gold. Then I left it over night, when the gold settled. well, I grew a crystal garden. So before I go and mess it up even more I thought I would share it with you guys and see what you think
BTW I will use the as a learning lesson so please dont beat me up too bad. Also there is a lot of gold powder under those crystals
