Perhaps its most distinctive feature though, is its very high density (high specific gravity). 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. Cut-Off grade is the minimum grade required in order for a mineral or metal to be economically mined (or processed). Material found to be above this grade is considered to be ore, while material below this grade is considered to be waste. Although in a variety of units can be used, the cut-off grade is usually expressed as: g/t (grams per tonne)The most common ore mineral of lead mined in the United States is galena with the chemical symbol PbS. Galena is lead sulfide with a hardness of 2.5 on the Moh's scale - actually quite soft- but it is VERY heavy with a specific gravity of 7.4 to 7.6. To put that in perspective, it weighs about 700 pounds per cubic foot! Amphiboles are a mineral group with a vitreous, dull, or opaque luster.

Pyrrhotite is similar to another iron sulfide mineral named troilite. Troilite has a chemical composition of FeS, while pyrrhotite's chemical composition is Fe (1-x) S. Pyrrhotite is deficient in iron because some of the iron sites in its crystal lattice are vacant (empty). That is why the iron in the formula has a subscript of 1-x.Classes of Minerals. Minerals are classified according to their chemical properties. Except for the native element class, the chemical basis for classifying minerals is the anion, the negatively charged ion that usually shows up at the end of the chemical formula of the mineral. For example, the sulfides are based on the sufur ion, S 2–.
