Processes and Procedures in the Extraction of Iron ...


The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres.

Mar 14, 2014· Processing of the ore ranges from simple crushing and screening and separating various size fractions of the ore to the processes that beneficiate or upgrade the quality of the iron ore products. This is done by physical processes, which remove impurities by difference in particle density or size gravity or size separation.

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 ...
