2.2 Mineral Groups Most minerals are made up of a cation (a positively charged ion) or several cations, plus 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). The two Fe 3+ ions have an overall charge of +6 and that balances the overall …

The iron minerals that are at present used as ores are hematite, magnetite, limonite, and siderite; also, occasionally ankerite, goethite, and turgite. Hematite is the most important iron ore. The iron content of the pure minerals is as follows: Ankerite is a carbonate of lime, magnesia, manganese, and iron.
The two metals are closely connected, starting with their mineralogical occurrence in combined lead-zinc ores (i.e., combination of mainly lead sulfide, zinc sulfide, iron sulfide, iron carbonate, and quartz) that are processed in the primary industry and hence interlink the production routes. Both metals have very high recycling rates.
Ore is a deposit of one or more precious minerals in the Earth's crust. The most important ore deposits, such as copper, silver, and iron, contain metals that are essential to industry and trade. Copper ore is mined for a wide range of industrial applications. Copper, an exceptional electricity conductor, is used as an electrical wire.
