Galena mineral formula

Graphite is a mineral of extremes. It is extremely soft, cleaves with very light pressure, and has a very low specific gravity. In contrast, it is extremely resistant to heat and nearly inert in contact with almost any other material. These extreme properties give it a wide range of uses in metallurgy and manufacturing.

(more below) Galena is a soft mineral of Mohs hardness of 2.5, a dark-gray streak and a high density, around 7.5 times that of water. Sometimes galena is bluish gray, but mostly it's straight gray. Galena has a strong cubic cleavage that is apparent even in massive specimens.Galena. Con el nombre de galena se designaba antiguamente a los minerales de plomo pero también las escorias de plomo fundido. Plinio lo utilizaba con este último sentido. Actualmente ese término hace referencia al sulfuro de plomo, mineral de fácil distinción debido a sus característicos cristales cúbicos de color gris plomo y brillantes.Description and Identifying Characteristics Its perfect cubic cleavage, metallic luster, lead-gray color, and relative softness readily distinguish galena from most other metallic minerals. Perhaps its most distinctive feature though, is its very high density (high specific gravity). Galena is a silvery mineral and the most important lead ore. It melts at a low temperature and was first smelted in prehistoric campfires. Thousands of years later, it would be instrumental in creating the first radios and other electronics.
