Recover Gold without Chemicals (3 replies and 2 comments)
By stating you want chemical free recovery of gold, I am assuming you are limiting yourself to gravity separation means. Even if you wanted to consider bio/bacterial leaching as chemical free, it would be so until you needed to control pH, then chemicals would enter the arena.
Gravity separation of gold from ore(s) is fairly straight forward and described in an abundance of locations/media. Gravity separation of gold from electronic waste would, however, present a more significant problem.
I hope this helps some.
Hi Jeff
I hope that you are well in our crazy world where no one seems to know what is going to happen next.
I'm based in the UK and am looking at methods for non chemical gold recovery from CPU's as you have been discussing with Charlie, did you design and build your system or did your purchase it from the market place? I am very interested in progressing an environmentally friendly system here in the UK so would appreciate the opportunity of learning a little from your obvious experience.
Look forward to your reply, take care in a crazy world
Kind regards

Hello guys, I am hoping to get your best recommendations for various gold extraction or recovery methods for non chemical gold recovery.
Situation #1: recover gold from scrap electronics
Situation #2: recover gold from rock I consider ore. Here there are no other base metals associated with it.
Thank you!
Charlie
