iron ore is a mineral substance which when heated in the presence of a reductant will yield metallic iron fe. the iron ore usually very rich in iron oxides fe3o4 and fe2o3. iron ores are mostly dark grey to rusty red in color and high specific gravity. two main types of iron ore used for iron makingmagnetite fe3o4 and hematite
a portion of the reductant is screened out for use as a recarburising agent for the iron. smelting process. the smelting technology used at rbm was originally developed and proven at quebec iron and titanium qit fer et titane in sorel canada where coarse ilmenite is smelted to produce a hightio 2 slag and pig iron in similar furnaces. this technology was adapted for rbm to process the fine ilmenite
iron ores are rocks from which metallic iron can be economically extracted. these rocks are usually found in the form of hematite fe2o3 or magnetite fe3o4. about 98% of world iron ore production is used to make iron in the form of steel. nearly all of earths major iron ore deposits are in rocks that formed over 1.8 billion years ago.

the course is designed to explain what the users of iron ore are looking for in both physical and chemical properties and how processing the ore can create the necessary properties. participants will look at the typical types of iron ore deposits and how each may
jan 04 2007· screening is an important step for dry beneficiation of iron ore. crushing and screening is typically the first step of iron ore beneficiation processes. in most ores including iron ore valuable minerals are usually intergrown with gangue minerals so
iron ore can be upgraded to a higher iron ore content through beneficiation. this process generates iron ore filter cake which needs to be pelletized to be used in the steel making process. also during the processing of high grade iron ores which dont need beneficiated fines which are generated can be pelletized and used instead of being disposed of. iron ore pellets are formed from beneficiated or run
