processing of iron ores

Dry Iron Ore Beneficiation | ST Equipment Technology

Iron ore extraction is mainly performed through open pit mining operations, resulting in significant tailings generation. The iron ore production system usually involves three stages: mining, processing and pelletizing activities. Of these, processing ensures that an adequate iron grade and chemistry is achieved prior to the pelletizing stage.

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 ironbearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is red; magnetite .

Developing a zerocarbon method for processing iron ore

 · The current method for processing iron ore is by melting it in a blast furnace, causing the iron oxide to separate from the other parts of the ore. Hot oxygen interacts with coal in the furnace to create carbon monoxide (CO), which then interacts with the iron oxides, taking up the oxygen to become carbon dioxide (CO 2 ), and leaving plain iron ...
