Hello Refiners,
this is the first time I'm going to recover gold from electronic scrap with electrolysis cell using NCL as leach solution (cyanide substitute)
the scrap that I'm about to use is sound cards, pci cards, mother boards, ram cards, Tektronix old oscilloscope cards and mil spec total gold plated aluminum boards.
Some cards have only gold plated fingers, others have tiny gold threads, some others look heavy plated like those of oscilloscope and the mil spec aluminum ones, and others have only tiny holes with plated borders additionally to their fingers.
My questions are:
1. should I cut off and process only the fingers when there is no significant amounts of gold in a card? ( I do not want to degrade very fast my chemical solution).
2. Should I process without cutting off fingers and put all of them in one piece?
3. should I process some types of cards separately?
4. should i smash with a hammer blow only the microprocessors or are there any black smaller chips that have some gold inside.
As you can see these are perhaps a bunch of silly question, I would gladly appreciate any help since this is quite a breakthrough for me.
Sincerely,
Tutorus
