In fact it's very common that the gold in hard rock ores will range in the 30 to 200mesh size range with most of the gold in the lower end of that range. The tried and true method for testing these ores in the field is hand crushing and panning. Pan testing for free gold was done extensively by the old timers all over the world.

Real gold is soft and malleable. So when pressure is applied to it, gold flattens. Pyrite, on the other hand, is brittle. It shatters easily when hit. You can test whether a piece is fool's gold by sticking a pin in it. Gold should just be dented, whereas pyrite should crumble at the spot where the pin is being stuck.
· Pyrite, also known as fool's gold, has a metallic yellow appearance, but several tests can distinguish it from real gold. It has a hardness rating of 6 or more, while gold is much softer, with a rating between 2 and 3.  It leaves a greenishblack streak, and can be crushed into powder if enough pressure is applied.
Acid Test: This is a simple test that capitalizes on the reaction of gold with acid to prove its originality. All you have to do is make a slight scratch on the surface and add a small drop of trioxo nitrate (v) acid (HNO3). If the gold does not react with the acid, this is a proof that we're dealing with real gold.
The best answer as to how to recover that gold depends on the amount of pyrite you intend to process. If you have only a few pounds, it can be roasted by heat in the open air and then mixed with a flux like sodium borate and melted with a collector metal like copper. The melt can be poured into a mold and the gold will now be alloyed in the copper.
