What is Tetrahedrite Ore?

Tetrahedrite is a sulfide mineral belonging to the tetrahedrite group, with the chemical formula (Cu,Ag)12Sb4S13. It is considered a primary ore of copper and can also be a significant source of silver, iron, and zinc. The mineral is characterized by its complex chemical composition, where copper is the predominant metal, but silver, iron, and zinc can substitute extensively within its crystal structure. This solid solution series is why tetrahedrite often grades into tennantite, which has arsenic instead of antimony as the primary chalcogen. The high copper content makes it an economically important ore, especially when found in substantial concentrations.

The ore typically appears as dark gray to black, opaque crystals with a metallic luster. It often occurs in massive or granular forms rather than well-defined crystals, especially in ore deposits. Tetrahedrite is found in hydrothermal veins and is commonly associated with other copper minerals like chalcopyrite, bornite, and chalcocite, as well as silver minerals. Its hardness is relatively low, ranging from 3 to 4 on the Mohs scale, with a specific gravity of about 4.8 to 5.2. The economic value of tetrahedrite ore lies in its potential to yield both copper, a fundamental industrial metal, and silver, a precious metal used in electronics, jewelry, and investment.

Composition and Variations

The ideal formula for tetrahedrite is Cu6[Cu4(Fe,Zn)2]SbS13. However, natural tetrahedrite is rarely pure. It forms a solid solution series with tennantite, where arsenic (As) replaces antimony (Sb). The general formula is often represented as (Cu,Ag)10(Fe,Zn)2(Sb,As)4S13 to account for these substitutions. The amount of silver (Ag) can vary significantly, with some varieties being particularly rich in silver, hence they are often referred to as silver tetrahedrite or freibergite when the silver content is high (approaching Ag12Sb4S13). Iron (Fe) and zinc (Zn) also commonly substitute for copper. These variations influence the ore’s processing and overall economic value.

Physical and Chemical Properties

Tetrahedrite ore exhibits a metallic luster and is opaque. Its color ranges from dark steel-gray to black, sometimes with reddish or greenish tints due to impurities. It has an imperfect cleavage and a fracture that is typically conchoidal to uneven. The mineral’s hardness of 3-4 makes it relatively soft and susceptible to abrasion. Its specific gravity is around 4.8 to 5.2, varying slightly with composition. Chemically, it is primarily a source of copper and antimony, but when argentiferous, it is also a crucial source of silver. It is relatively stable but can tarnish when exposed to the atmosphere.
