What is Chalcopyrite?



Chalcopyrite is a copper iron sulfide. It is the most commonly encountered copper mineral and is the most important ore of copper. Chalcopyrite deposits are found in hydrothermal veins, void fillings and replacements in limestones, contact metamorphic deposits and magmatic separations. Minor amounts are found throughout many igneous, metamorphic and sedimentary rocks.
