iron processing

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 …

Iron ore crushing process. In the iron ore crushing process, the feeder, first crushing, secondary crushing, screening, fine crushing and dry selection are generally used. For the sake of economy, generally the finer the ore particle size entering the dry separator, the higher the proportion of iron-bearing ore that is dry selected.

Direct reduced iron

Process. Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to remove the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)).
