Galena | Common Minerals

Galena is the most abundant lead mineral, has been mined for millennia, and remains our major source of that metal. It is a metallic, lead-gray mineral with cubic cleavage and a distinctly high density that makes galena samples feel much 'heavier' than expected for their size. Because it melts at a relatively low temperature and is so ...

Lead Sulfide

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.
