GOLD!
There is gold dust in this rock too but not as rich as the sooty-black rock from the quarry. I have no idea what this rock is. It''s not quartz or limestone. Not hard enough for an igneous rock like basalt. Not brittle like chalcedony. Kind of like a carbonized type of metamorphic rock.

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.

Do all quartz deposits contain gold?
Answer (1 of 12): No they do not. Quartz is common, gold is rare. Quartz veins typically form when very hot water rising from depth flows into a shallow crack in the rock. The dissolved silica precipitates as quartz. If there is gold present in the water, it will also precipitate. The result is

How fine to crush rock for panning (Page 1) / Alluvial
Anyways I brought some rocks back (ironstone and quartz in a hardened clay) and crushed the heck out of them then tried panning. Well I’m not sure but I don’t think there was any gold in them, but I don’t think I would have been able to spot it if there was. I crushed the rock till it was dust, I don’t think I could have crushed it more.

Testing Ores for Free Gold
One of the points I want to make sure to mention is that rock crushing needs to be done safely. Quartz is made of silica, and silica has a terrible effect on one’s lungs if you breathe too much of it. In all the crushing I am doing, I use a good quality dust mask with a HEPA Filter (not just one of those little white paper ones).

How gold is extracted by Cyanidation Process
Using a heavy metal, smash the crushed rocks further until it is in the form of a powder. Ensure that the result is finer than sand. This process helps in getting all the gold from the rocks. The amalgamation process then helps in separating gold from the rock by adding mercury to the finely powdered rock-gold.
