Iron ore exists in igneous rocks, metamorphic rocks (metamorphic rocks) or sedimentary rocks in various geological environments. Most of the environment is sediment, but many are changed due to weathering, so it is difficult to determine the sourc...

Iron processing Ores Britannica

Iron processing Iron processing Ores: 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

Crushing Vs Grinding Minerallurgy

For crushing no grinding media is required, the ore size is reduced by external forces applied by the crusher. Dry crushing but wet grinding. Crushing is usually a dry process, while milling is performed with water. The advantage of wet milling is the lower energy input compared to dry milling.
