2.3 Mineral Groups – Physical Geology - opentextbc.ca

2.3 Mineral Groups Most minerals are made up of a cation (a positively charged ion) or several cations and an anion (a negatively charged ion (e.g., S 2–)) or an anion complex (e.g., SO 4 2–). For example, in the mineral hematite (Fe 2 O 3), the cation is Fe 3 + (iron) and the anion is O 2– (oxygen). We group minerals into classes on the basis of their predominant anion or anion group.

Iron processing - Ores | Britannica

Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is red; magnetite (Fe3O4), which is black ...

The carbonates include minerals in which the anion is the CO 3–2 complex. The carbonate combines with +2 cations to form minerals such as calcite (CaCO 3 ), magnesite (MgCO 3 ), dolomite ( (Ca,Mg)CO 3 ), and siderite (FeCO 3 ). The copper minerals malachite and azurite are also carbonates. In phosphate minerals, the anion is the PO 4–3 complex.
