Mineral Many sulfide minerals are economically important as metal ores; examples include sphalerite (ZnS), an ore of zinc, galena (PbS), an ore of lead, cinnabar (HgS), an ore of mercury, and molybdenite (MoS, an ore of molybdenum. Pyrite (FeS), is the most commonly occurring sulfide, and can be found in most geological environments. It is not, however, an ore of iron, but can be instead oxidized to produce sulfuric acid. Related to the sulfides are the rare sulfosalts, in which a metallic element is bonded to sulfur and a semimetal such as antimony, arsenic, or bismuth. Like the sulfides, sulfosalts are
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). When several Ore Mountain passes were upgraded into "chaussees" in the 19th century, and the Upper Ore Mountains were accessed by the railway, tourism began to develop. One of the early promoters of tourism in the Ore Mountains was Otto Delitsch. In 1907, a memorial was erected to him
