Heretofore the basic concept behind most magnetic roasting processes has been the idea of heating iron ore to a temperature of 800° to 1100°F in a strong reducing atmosphere, preferably either carbon monoxide or hydrogen. Temperatures under 800 °F were undesirable since excessive roasting time was required.

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 processing Iron ore magnetite processing (LIMS, MIMS, WHIMS, Davis Tubes) The increased worldwide demand for steel in recent decades has led to an increase in …
