Non-silicate minerals
Non silicate minerals are minerals that do not contain the silica tetrahedron and are made up of other elements. They comprise 8% of Earth’s crust and are common in sedimentary rocks; most have industrial applications. There are six main groups:
| Group | Description | Example |
|---|---|---|
| Carbonates | Contain the carbonate ion (CO32+) | Calcite (CaCO3) |
| Oxides | Contain the oxide anion (O2−) | Hematite (Fe2O3) |
Native Elements |
These minerals occur in nature as an element and combined together to form a mineral structure, either solely comprised of the same element or mixed together as an alloy. | Diamond (C) |
| Halides | Contains a dominant halide anion (F−, Cl−, Br− and I−) | Halite (NaCl) Fluorite (CaF2) |
| Sulfides | Contains sulfide (S2−) | Pyrite (FeS2) |
| Sulfates | Contains the sulfate anion (SO42−) | Gypsum (CaSO4·2H2O) |
