Is tetrahedrite a Sulfosalt?

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.

Where is tetrahedrite mined?

Tetrahedrite is an sulfide mineral of antimony, copper and iron with the composition (Cu,Fe)12Sb4S13 . This sample is about 14×14 cm and is from Mercedes mine, Huanuco, Peru. Tetrahedrite is mined as an ore of copper. These crystals of tetrahedrite were found lining and underground cavity in the Andes Mountains.

How is chalcopyrite formed?

Chalcopyrite is an accessory mineral in Kambalda type komatiitic nickel ore deposits, formed from an immiscible sulfide liquid in sulfide-saturated ultramafic lavas. In this environment chalcopyrite is formed by a sulfide liquid stripping copper from an immiscible silicate liquid.

What is the characteristics of tetrahedrite?

Tetrahedrite gets its name from the distinctive tetrahedron shaped cubic crystals. 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.

Why is chalcopyrite called fool’S gold?

Pyrite is called “Fool’s Gold” because it resembles gold to the untrained eye. While pyrite has a brass-yellow color and metallic luster similar to gold, pyrite is brittle and will break rather than bend as gold does. Gold leaves a yellow streak, while pyrite’s streak is brownish black.

How much is fools gold worth?

“Fool’s gold” is a common nickname for pyrite. Pyrite received that nickname because it is worth virtually nothing, but has an appearance that “fools” people into believing that it is gold.

How can you tell the difference between gold and chalcopyrite?

Chalcopyrite in Dolomite and Quartz: Gold-colored minerals can be tested even if they are embedded in a rock. The gold-colored mineral in this rock is chalcopyrite, and a person could determine that it is not gold by poking the gold-colored material with a pin and observing if it dents or breaks.

Does fool’s gold stick to a magnet?

Iron pyrite will stick to the magnet because of its high iron content; gold will not. You can also use a drop of nitric acid to test your specimen. (Caution is advised.) Nitric acid will turn iron pyrite black, but gold will remain the same color.
