The galena samples contained 85.6% lead and 13.0% sulfur by weight. X-ray diffraction analysis of the galena sample and leached solid product showed that the galena d-spacings are almost identical to those of the ASTM values and also that the solid product formed after leaching is pure elemental sulfur.

It is lead sulfide (PbS). When pure, it contains 86.6% lead and 13.4% sulfur. Galena is metallic lead gray with a bright metallic luster when freshly broken, and dark gray to black when weathered. It is brittle and very heavy (about 7.6 times as heavy as water). Galena most commonly forms cubic crystals, and breaks with perfect cubic cleavage.
