Or pan the gold manually in water to separate gold from the gravel and sand in a stream. Refine the gold you have extracted and separated. Use Miller and Wohlwill processes, which process gold chloride by subjecting it to an electric current; this separates gold from impurities and attaches it to the anodes generating the current.
Prospecting for gold can be a fun hobby, though it's a lot of work! You may be able to harvest gold flakes from rock if it contains gold among its minerals. The safest way to extract gold from rocks at home is to crush the rocks. However, you might use mercury to extract the gold if you're able to obtain some, though this is dangerous.

2.2.2. Typical Metallurgical Reagents Present in Gold Mine Tailings . The chemical reagents used in the metallurgical process of gold beneficiation are similar to those presented for the case of copper; therefore, Table 1 is valid for this case as well. In gold mining, a dilute cyanide solution is poured over the crushed and ground rock.
You will hear of a lot of people using magnets, Im not real keen on this idea the reason been. If there is a very heavy display of mineral sands and you try to drag the mineral sands back from the gold the sand will trap gold and pull it down with it. The stronger the magnet the more trouble you will have, you are much better off using water.
Scientists accidentally discover a new way to isolate gold that is much safer than existing processes, which use toxic cyanide. Gold, precious forever but especially lately, is a tricky metal.
I use a modified Keene A-52 sluice. It has some NoTrax matting glued in the top to catch fine gold. I then start the engine on the dredge at idle so the water runs down the shovel sluice. I adjust the engine so that the water flow is swift enough to wash out light sand and still save all of the black sand and gold.
