This is the main difference between them. The chemical formula of pyrite is FeS2; it is sulfide compound of iron where as galena is sulfide compound of lead with the chemical formula PbS. The color of galena may vary from light gray to dark gray while pyrite is generally brass yellow in color. Particles can either be naturally hydrophobic, or the hydrophobicity can be induced by chemical treatments. Naturally hydrophobic materials include hydrocarbons, and non-polar solids such as elemental sulfur. Coal is a good example of a material that is typically naturally hydrophobic, because it is mostly composed of hydrocarbons.Galena is by far the greatest ore of lead.
