Miners who process gold ores will get free gold particles that can be melted into bars, but they also recover pyrite that has small amounts of gold within it. Often the majority of the gold is in the free particles, but sometimes the pyrite can also contain important amounts of gold. It is not easy to get the gold out of that pyritethere is
