Galena of Missouri and Wisconsin; the former mining communities of Galena, Kansas and Galena, Illinois take their names from deposits of this mineral. The largest documented crystal of galena is composite cubo-octahedra from the Great Laxey Mine, Isle of Man, measuring . Galena belongs to the octahedral sulfide group of minerals that have metal ions in octahedral positions, such as the iron sulfide pyrrhotite and the nickel arsenide niccolite. The galena group is named after its most common member, with other isometric members that include manganese bearing alabandite and niningerite. Divalent lead (Pb) cations and sulfur (S) anions form a close-packed
Ore Mountains mining in the southern forelands of the Ore Mountains. Europe's largest deposits of lithium-bearing mica zinnwaldite in Cínovec, a Czech village between town of Dubí and the border with Germany which gave its old German name Zinnwald to the mineral, are expected to be mined starting 2019 (as of June 2017).
