Germanite

 

a mineral of the group of complex sulfides; chemical composition Cu3(Fe,Ge)S4. The germanium content is 7-10 percent; insignificant amounts of zinc, lead, gallium, and arsenic are present. Most researchers attribute germanite to the cubic (or pseudocubic) system. Crystals are unknown.

Germanite is usually found in the form of separate nodules, exudations, or solid bodies in close association with pyrite, gray copper ores, sphalerite, or galena. It is brownish pink with violet shadings and is opaque, with a metallic luster. Its hardness on the mineralogical scale is 4.0; density, 4,400-4,600 kg/m3. It has been discovered in hydrothermal copper-polymetallic deposits. It is an important source of germanium. The only known commercial deposit is located at Tsumeb in Namibia (South West Africa).
