Free Gold is liberated and depending on its size will be visible in a pan. Free Milling Gold is the gold that can be liberated by a standard rotating ball mill. Refractory Gold is that which is not recoverable by standard milling and/or chemical processes. This may be 'entrapped in sulfides'. A standard ball mill may grind your ore to 75 microns.
