Once you have removed nearly everything but the gold, use your magnet and stir the material at the bottom of the pan to pick out the remaining fine textured sands. Once finished with this wet separation process, you should be down to almost clean gold. Dry whatever you have left and inspect it carefully.
Water conservation in the coal beneficiation process is another element of the company''s RD. It is exploring practical options for dry separation technology for coal plants, in collaboration with a local university. Traditional waterbased coal washing technology is a major consumer of water in mine plants.
