Nice video. But I think most here are more interested in gold recovery from e-waste because it's chemically more challenging.
Any idea how profitable your process is? Selling price of high purity gold minus cost of gold scrap minus cost of chemicals and energy?

kadriver - that was a really great video! I was always curious how people handled gold recovery. When I saw you fumble the paper holding the gold I
was very concerned how your technique would be. Turns out you have excellent technique.
I was wondering though. How worth it was the burning of the filter paper and employing borax rather then letting the filter paper dry and removing the
gold mechanically? I could be wrong, but it seemed like a lot of the cloudiness in your second precipitation was due mostely to having digested that
other filter paper.
Anyways, really great and inclusive video. I hope you keep making things like this.
