Galena, a natural mineral form of lead sulfide, is a natural source of silver and the main ore for lead. It's one of the most abundant and widely distributed sulfide minerals. It is often associated with the minerals sphalerite, calcite and fluorite. One of Galena's earliest uses was in the eye cosmetic kohl used by the ancient Egyptians. It's the official state mineral …

Galena. Chemical Composition: PbS. Color: The mineral, if fresh, is bright silver in color with a metallic luster and dulls into a lead grey color as it tarnishes (1). Cleavage/Fracture: Cleavage is perfect, cubic with three directions at right angles. Crystal Form: Crystals may occur as cubes, octahedrons, or a combination of the two forms.

Galena is the primary ore mineral of lead. Worked for its lead content as early as 3000 BC, it is found in ore veins with sphalerite, pyrite, chalcopyrite, tennantite-tetrahedrite, etc. and in skarns, as well as in sedimentary rocks where it may replace carbonate beds or be deposited in pore spaces. The crystals are bright when fresh but often ...

Cerussite (PbCO 3) and angle site (PbSO 4) commonly occur in the near-surface weathered or oxidized zone of a lead ore body. Deposits containing lead form from hot (hydro thermal) fluids generated within the earth which may be trapped below the surface in cracks where galena and other minerals may precipitate to make vein deposits."

Galena is the natural mineral form of lead sulfide (PbS). The mineral occurs as fine to large crystals due to syntectonic remobilization at low temperature and move to a suitable location. The color is shining lead-gray and silvery (Fig. 1.39) with high specific gravity between 7.2 and 7.6 g/cm 3 containing 86.6% Pb in the purest form.Most of the galena …
