Sulfide minerals can provide important clues for smallscale gold miners and prospectors in loing both placer and lode deposits. This is especially true when it comes to lode or vein gold. The following are some of the main sulfide mineral indiors you should keep an eye out for when prospecting. Bear in mind, mineral indiors.
Chalcopyrite is a common mineral and is found in almost all sulfide deposits. Fine crystals of chalcopyrite have a unique character and can add to anyone's collection. As an ore of copper, the yield of chalcopyrite is rather low in terms of atoms per molecule. It is only 25%, compared to other copper minerals such as chalcocite, Cu2S 67%; cuprite, Cu2O 67%; covellite, CuS 50% or bornite ...

In Newfoundland, sphalerite has been mined at a number of loions, including Buchans, in association with galena and chalcopyrite, and at Daniel's Harbour, on the Great Northern Peninsula, which was a "Mississippi Valleytype" deposit and had cadmium as a byproduct.
Some Spanish chalcopyrite and pyrite bodies have been continuously mined for over three thousand years to produce copper and sulfur, along with other associated minerals such as gold. More recently, copper's high conductivity, softness, and resistance to corrosion, have given it a critical role in generating and distributing electrical power.
· Chalcopyrite [CuFeS2] is a copper iron sulfide that is often confused with the iron sulfide, pyrite [FeS2]. Both are sort of a brassy yellow color and tarnish upon exposure to oxygen. Chalcopyrite is much softer ( Mohs) than pyrite (). Pyrite (Isometric Crystal System) often occurs as cubes but sometimes as octahedrons and ...
