How do you separate gold from other substances Finishing

1). One way is by 'panning'; since gold is heavier than most other substances, you can swirl water just fast enough that the gold stays in the pan while the other substances wash out. Or, 2). You can put everything into an acid that dissolves other substances and doesn't dissolve gold. Or, 3).
