Hi I recently discovered refining gold and other metals from electronic scrap and I am pretty enthused about it. I acquired some scrap the past two-three weeks and am setting up for my first gold recovery:
Acquired scrap consists:
17 K6
29 Athlon (17 ceramic, 9 brown board, 3 green board)
1 lb. full ram sticks
10 lb very high grade, vintage looking board, already trim and without other components, covered in gold
Materials acquired thus far:
500ml 70% Nitric
1 pound urea
1 pound sodium metabisulfite
ceramic melt dishes
Pending materials:
1 gal. muriatic acid from the local hardware store
some sort of buckets
torch(es)
safety equipment
filter
Draft procedure:
de-lid the k6, crush
crush the athlon
trim fingers and remove memory chips off the ram, crush the memory chips
shred the 10lbs of board
put the results into a bucket
add 1:3 nitric to HCL
wait
filter out solution to another bucket
check for remaining gold, might aqua regia the scrap again, filter, etc.
neutralize with urea
precipitate with sodium metabisulfate
pour off
dry the precipitant
melt
_________
Obviously a rudimentary procedure, I might use a sulfuric method in the future since I sourced a 55 gal barrel for $180. I found nitric 2.5L for $65 or $70 though I overpaid for the nitric I got for this refinement 2x. I read technical grade nitric is pretty cheap so who knows but $3.27 gal for sulfuric seems reasonable. I'll continue to read and read the materials on this site and on scribd, etc. but I am planning on refining next week or so so it would be good to get some potential veteran input.
