·Uses Hematite is used in the extraction of iron for the manufacture of steel which is the most popular application of the vast quantity of hematite ore mined is then processed into iron and applied in the manufacture of steel items Hematite has higher iron content and lower impurity levels than magnetite which makes it a more suitable iron source
·Diagram showing the carbon extraction of iron The raw materials iron ore hematite coke an impure form of carbon and limestone are added into the top of the blast furnace the symbol equations are not needed for the different reactions involved in the extraction of iron from hematite Equations for extraction of iron from hematite
Different processes are then used to produce a more highly concentrated form of iron metal from the small pieces of iron containing ore bauxite and limestone Hematite is an ore of iron bauxite is an ore of aluminum and limestone is an ore of calcium As the blast furnace is used for the extraction of iron we are interested in answers
·Iron ore tailings IOTs specifically those generated from iron ore beneficiation plants present notable challenges to both the environment and economic sustainability For example magnetite rich IOTs necessitate magnetic separation while hematite rich ones may require different methods Secondary phases such as clay associated minerals
