Gold in Quartz
Crushing the ore can free the gold and allow recovery by gravitybased methods. 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.
