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.

Rock gold mainly chooses the appropriate gold processing method according to its composition. Commonly used gold processing methods are mainly the gold cyanidation process, gold flotation process, and gold gravity separation process. Method #1: Gold cyanidation process. The cyanidation process is one of the main methods of extracting gold from ore.
