Answer: The classifications of ores based on the negative radical present in them include sulfide ores, carbonate ores, oxide ores, halide ores, and sulfate ores. Some examples are:
1. Sulfide ores - Galena (PbS), Chalcopyrite (CuFeS_2), Sphalerite (ZnS), Pyrite (FeS_2), Cinnabar (HgS)
2. Carbonate ores - Calcite (CaCO_3), Dolomite (CaMg(CO_3)_2), Siderite (FeCO_3), Smithsonite (ZnCO_3), Malachite (Cu_2(OH)_2CO_3)
3. Oxide ores - Hematite (Fe_2O_3), Magnetite (Fe_3O_4), Bauxite (AlO(OH)), Cassiterite (SnO_2), Cuprite (Cu_2O)
4. Halide ores - Fluorite (CaF_2), Halite (NaCl), Sylvite (KCl), Carnallite (KMgCl_3·6H_2O), Cryolite (Na_3AlF_6)
5. Sulfate ores - Gypsum (CaSO_4·2H_2O), Anhydrite (CaSO_4), Barytes (BaSO_4), Kieserite (MgSO_4·H_2O), Celestite (SrSO_4)
