One most promising technique of pinpointing gold in the midst of rocks is through thrashing it with a hammer. Cut off a piece of the rock-like substance you think is gold and strongly crash it with a hammer. When smashed with a hammer, gold automatically flattens out while other kinds of rocks will turn to dust or powder. That said, when after crashing the rock in question you discover that it flattens instead of crumbling, you should definitely know that you have found gold. Nevertheless, some rocks flatten when smashed with a hammer hence it is ideal you to take a piece of the rock for further testing to confirm your doubts before you go ahead to mine it.

Another superb way to tell between gold and other rocks is through melting or dissolving it in acids. Gold is the only known rock that melts at an extremely low range of 2.5 to 3. It is also the only rock which doesn’t dissolve in acids but quickly liquefies when exposed in a blend of hydrochloric acid and nitric acid. If during your hunt for gold you come across a rock which resembles gold in all physical characteristics but you aren’t sure if it is really gold, you should cut a piece of such a rock and strongly heat it or toss it in a container containing a mixture of nitric acid and hydrochloric acid. If it melts at 2.5 when heated or dissolves in the mixture of the two acids, you should go ahead to mine it.

Pure gold doesn’t include other elements such as irons. It is free on its own. Most other rocks which reside alongside gold include pieces of iron. What this means is, when you place a magnet against these rocks, they will easily get attracted to such magnets. On the other hand, if you place a magnet against gold, it will stay still. This leads us to our next most awesome way to identify gold in rocks. When in discover gold in the midst of rocks and you want to tell if it is really gold, a magnet will be an essential tool to use in determining the kind of precious metal you have landed yourself into.

The last most effective way to identify gold amongst rocks is through conducting a streak test. A streak test is a simple method of rubbing a rock against a streak surface. When rubbed against rocks, gold usually produces a bright yellow powder. Before you set for a gold hunting journey, you must find yourself a good quality streak plate. There are lots of these plates in majority of online hobby and mineral shops.
