After carbonates, the next most common non-silicate minerals are the oxides, halides, and sulfides. Oxides consist of metal ions covalently bonded with oxygen. The most familiar oxide is rust, which is a combination of iron oxides (Fe 2 O 3) and hydrated oxides. Pyrite and Galena are both naturally occurring minerals, but they differ in their chemical compositions. Pyrite is iron sulfide, represented by the chemical formula FeS2. In contrast, Galena is lead sulfide with the chemical formula PbS. Fiza Rafique. Sep 29, 2023.
