Classes of Non-Silicates

Native Elements Contain: composed of only one element Examples: gold (Au), silver (Ag), Sulfur (S), Copper (Cu), Iron (Fe), Carbon (as diamonds or graphite)

Native Elements Uses: Jewelry and wiring

Carbonates Contain: O2, C Examples: calcite (CaCO3), dolomite (CaCO3)

Carbonates Uses: fireworks, gunpowder, cement, building stone

Halides Contain: F, Cl, I, Br combined with Na, K, Ca Examples: Halite (NaCl), Flourite (CaF2)

Halides Uses: rock salt and fertilizer

Oxides Contain: Al or Fe combined with O2 Examples: Corundum (Al2O3), Magnetite (Fe3O4)

Oxides Uses: abrasives, air crafts

Sulfates Contain: S and O2 Examples: gypsum (CaSO4)

Sulfates Uses: white sand used for cosmetics, toothpaste, paint

Sulfides Contain: one or more Pb, Fe, or Ni combined with S Examples: Galena (PbS)

Sulfides Uses: batteries, medicines, electronic parts
