1) Oxides: Examples include hematite (Fe2O3), magnetite (Fe3O4), and corundum (Al2O3). These minerals are composed primarily of metal ions bonded to oxygen.

2) Carbonates: Examples include calcite (CaCO3), dolomite (CaMg(CO3)2), and siderite (FeCO3). These minerals are composed of carbonate ions (CO32-) combined with various metal ions.

3) Sulfides: Examples include pyrite (FeS2), chalcopyrite (CuFeS2), and galena (PbS). These minerals are composed of sulfide ions (S2-) combined with various metal ions.
