Hi all, I wanted to thank the creators of this forum for all the great information. I have been scrapping ewaste here in Maine for about a year now and have been very interested in learning the process of extracting PM's from electronics scrap. After loads of reading....Hoke takes a while, its not a suspense thriller or anything but man does it have great info. I came to the conclusion that the A/P method would be the easiest one for me to start with as it requires fairly little to get started. So i read lazersteves post on it, read it twice, ok read it about 10 times and watched his videos and finally started my first batch today. I started with 8 oz of gold fingers very neatly trimmed using more tips off this forum. Here are some pics of what is going on.
The First 3 hours of the batch were done outside then after the reaction calmed down a bit I added a bit more H2O2 to the HCL 31.45% mix making a total of 2 parts HCL and 1 Part H2O2 and brought it inside tha garage. I have it covered in a larger tupperware container for the night so my tools dont corrode. At the last agitation all i saw was a bunch of lovely foils floatng around.
I am going to let it go for another 36-48 hours and then start pulling out the cleaned finger boards. Thanks all for all the great info and support!!
