MORE INFORMATION ON CHALCOPYRITE Poor cleavage pretty much everywhere Twins on {112} and {012} It forms in igneous and metamorphic rocks and is common anywhere that sulfide minerals exists. It s often found with other copper sulfide minerals Copper can be removed by weathering and carried a short distance in solution, where it then redeposits and forms secondary minerals like malachite. The colors of the tarnish are caused by the presence of acids
MINING FOR ORE One of the primary ores mined for copper. It is only 25% copper (which is less than other ores have) but is much more abundant. There is a now closed mine in Bristol, Connecticut that mined copper from chalcopyrite. It operated from 1837 to 1953
USES OF CHALCOPYRITE As a healing Crystal (like pretty much every other mineral is). It increases happiness, joy, and belief in yourself. It is acknowledged as a stone of the mystic and it s good for meditation. It can also be used for healing and finding lost things. People also collect it because it looks cool
