Separating gold flakes and dust from black sand
A large amount of it is magnetite so I should be able to extract that part using magnets, but I am uncertain how to proceed with the remaining hematite in the mixture. Since the overall amount I have is fairly small, I'd prefer to find a chemical method since I figure it would allow me to extract the most gold possible from the mixture.
