gold extraction machine from circuit boards

  • Grinding down circuit boards?

    Oct 15, 2009I'm also wondering how somone could deal with extracting the metal from an entire circuit board, on the neighborhood level. Cherry picking the high-yield pieces is alright. What happens if you pulverize the board to very, very fine powder. Then, float the powder in water. Would all the metal settle and the non-mettalics float
