WebThe bismuth tellurides on average are slightly harder than molybdenite (H 2-2.5) and the cleavage planes are straight and mirror like while the molybdenite cleavage (H 1-1.5) planes are often distorted and wavy. In most cases the bismuth telluride minerals and molybdenite do not occur in the same deposits so both phases do not occur together. WebBecause lead is a primary element in galena, the mineral has a high specific gravity (7.4 to 7.6) that is immediately noticed when picking up even small pieces. Galena is soft with a Mohs hardness of 2.5+ and produces a gray to black streak. Crystals are common and they usually are cubes, octahedrons, or modifications.
