Great work. I must start to work with ore,whole area where I live is full with gold and gold mines so I must start thinking in that way,scraping e-waste is game in means of how much gold you got from material and I know professors from here that talk me that they took one rock from Jastrebac or Kopaonik(mountain)and get 5-10 grams of gold. Thanks for sharing you r knowledge with all of us. Wish you luck in future.
