How is chalcocite formed?
Description: Chalcocite is formed either as a primary vein mineral or, more typically, in supergene deposits where it forms as a result of the redeposition of copper from the breakdown of minerals such as chalcopyrite or bornite. … Chalcocite is thus used here to covering all of these species.
Where is Enargite found?
It occurs in the mineral deposits at Butte, Montana, San Juan Mountains, Colorado and at both Bingham Canyon and Tintic, Utah. It is also found in the copper mines of Canada, Mexico, Argentina, Chile, Peru, and the Philippines.
Where is Argentite found?
It occurs in mineral veins, and when found in large masses, as in Mexico and in the Comstock Lode in Nevada, it forms an important ore of silver.
Is Enargite an ore?
Enargite is a sulfosalt mineral that is an import ore of copper. Crystals are sometimes coated with a thin layer of Pyrite crystals, giving it a yellow appearance. Enargite is dimorphous with the mineral Luzonite, which forms in tetragonal crystals.
What is Enargite used for?
Uses: As a minor ore of copper and as mineral specimens.
What are coppers uses?
Most copper is used in electrical equipment such as wiring and motors. This is because it conducts both heat and electricity very well, and can be drawn into wires. It also has uses in construction (for example roofing and plumbing), and industrial machinery (such as heat exchangers).
