What is tetrahedrite mineral?
Tetrahedrite, common sulfosalt mineral, an antimony sulfide of copper, iron, zinc, and silver [(Cu,Fe,Zn,Ag)12Sb4S13], that is an important ore of copper and sometimes of silver. It forms gray to black metallic crystals or masses in metalliferous hydrothermal veins.

How is tetrahedrite mined?
Tetrahedrite is an sulfide mineral of antimony, copper and iron with the composition (Cu,Fe)12Sb4S13 . Tetrahedrite is mined as an ore of copper. These crystals of tetrahedrite were found lining and underground cavity in the Andes Mountains. This sample is described as tetrahedrite with chalcopyrite.
How is Galena used?
Uses of Galena Galena is a very important mineral because it serves as an ore for most of the world’s lead production. It is also a significant ore of silver. The number one use of lead today is in the lead-acid batteries that are used to start automobiles.
What does bornite look like?
Bornite has a brown to copper-red color on fresh surfaces that tarnishes to various iridescent shades of blue to purple in places. Its striking iridescence gives it the nickname peacock copper or peacock ore.
Is it safe to touch galena?
Galena is a lead sulphide mineral that is one of the primary ores of lead found around the world. The lead in Galena is toxic if inhaled or ingested from dust particles, but the mineral or rock containing the mineral can be handled safely if there is no lead dust present.
What is siderite used for?
Siderite has been used as an iron ore and for steel production. Material from Cornwall, England has been called “chalybite,” after the Greek word for steel, referring to its iron and carbon content.
What kind of mineral is tetrahedrite made of?
The mineral usually occurs in massive form, it is a steel gray to black metallic mineral with Mohs hardness of 3.5 to 4 and specific gravity of 4.6 to 5.2. Tetrahedrite occurs in low to moderate temperature hydrothermal veins and in some contact metamorphic deposits. It is a minor ore of copper and associated metals.
Where can you find tetrahedrite in the world?
Tetrahedrite occurs in low to moderate temperature hydrothermal veins and in some contact metamorphic deposits. It is a minor ore of copper and associated metals. It was first described in 1845 for occurrences in Freiberg, Saxony, Germany.
How is tetrahedrite used as a thermoelectric device?
California-based Alphabet Energy announced plans to offer a thermoelectric device based on tetrahedrite to turn heat into electricity. The company claimed that other thermoelectrics typically produce about 2.5 percent efficiency, while tetrahedrite could achieve 5 to 10 percent.
