Hi guys,
I'm maybe opening thread which was discussed here already, but I have to, because I'm standing in front of investment and I need to be sure, it will work.
Source materials: computer boards and other old electronics, hundreds of kilograms per month for beginning, later maybe tons.
Possible methods of treatment:
A) HAMMER MILLING:
- remove big aluminium/steel parts
- remove BGA's and flatpack chips from boards (gold can stay locked inside),
- hammer mill the rest,
- use magnet to remove steel parts
You will end up with mix of metals and silica. Using shaker table (or panning for beginning), you will get rid of mostly all silica parts. Residue looks like this (about 1/3 of weight of boards):
