Hello all,
I am new to the community.
I usually recover scrap copper, aluminium and brass from electronic waste for a hobby. However I have began recovering gold plated parts from computers etc...
I have a strong addiction to gold so I am hoping to recover some. This is intended as a hobby and not to make money. I'm a keen learner and have been reading some materials from the net. Have also read Hoke's book and some other.
So far I have been successful in leaching the gold from the parts. However I failed my first Aqua Regia gold drop.
I purchased some SMB and added it to my solution of
150ml HCL and 50ml nitric. I used Urea to kill off the nitric first. I added 2tsp of SMB, it reacted but only for a second or so then nothing. I let sit for a day but nothing dropped. So I used a copper pipe to cement the gold.
On Hoke's book she states to boil away the nitric with the addition of sulfuric acid into a syrup avoiding a crust.
So I followed this method, however the yield was so minimal. I think i lost some values in the boiling off part.
I recently purchased copperas with the intent of using it on my next batch. I would appreciate any advice on how to use it correctly aswell as any advice on how to properly precipitate gold from Aqua regia.
Cheers,
Johno
