Iron Ore Processing, General
Iron ore mining methods vary by the type of ore being mined. Currently, there are four main types of iron ore deposits, depending on the mineralogy and geology of the ore deposits. These are magnetite, titanomagnetite, massive hematite, and piso-litic ironstone deposits. For taconite iron ores, mining iron ore begins at ground level.

9 Ore Deposits and Economic Minerals – Mineralogy
9.1.3 Mineral Deposits, Ore Deposits, and Mining. A mineral deposit is a place in Earth's crust where geologic processes have concentrated one or more minerals at greater abundance than in the average crust. An ore deposit is a mineral deposit that can be produced to make a profit. Thus, all ore deposits are mineral deposits, but the reverse ...
