Like many other promising Gold recovery techniques before, this one may also end up in a drawer.
It utilizes some organic byproduct from the food industry to harvest Gold.
Sounds too good to be true - but hey, who knows?

The same gel used as a replacement for acitve carbon. Still need cyanide or some solvent for gold.
It's supposed to be more selective for gold ions than others.
It's been discussed a couple times recently.
