(mineralogy) Pb6Sb14S27A steel-gray orthorhombic mineral consisting of a lead antimony sulfide and occurring in crystals and in masses; has metallic luster, hardness of 3-3.5 on Mohs scale, and specific gravity of 5.30-5.35. Also spelled zinckenite. Zinkenite (named after the German mineralogist K. Zinken, who died in 1862), a mineral, a complex lead sulfide with the chemical composition PbSb2S4. Zinkenite, which usually contains admixtures of Fe, Cu, Ag, and As, crystallizes in the hexagonal system. It forms continuous granular masses, acicular crystals, and radiated aggregates. It is steel gray and iridescent and has a metallic luster. A brittle mineral, it has a hardness of 3–3.5 on Mohs’ scale and a density of about 5,300 kg/m3. Zinkenite is found in low-temperature and medium-temperature hydrothermal antimony and antimony-complex ore deposits, where it is associated with antimonite, sphalerite, and other minerals.
