· A similar processing flow sheet was described by Zhao (2008) for processing oolitic hematite ore associated with the Longyan Iron Mine of Xuan Steel in Hebei province in China. The ore contained 47.66% total Fe and was ground to 65% passing 74 µm ahead of gravity separation.
Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together. For this purpose, a traveling-grate machine is used, and the burning of fine coke (known as coke breeze ) within the ore generates the necessary heat.
· When the iron ore is extracted from the mine, it must undergo several processing stages. Six steps to process iron ore 1. Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher''s CSS …
· properties of magnetite Physical properties of hematite Principals of Iron Ore The principal of iron ores are hematite (Fe2O3) and magnetite (Fe3O4). hematite: reddish-black mineral consisting of ferric oxide. It is an important ore of iron magnetite: a grey-black
To purify and strengthen iron, materials like coke are mixed in with it to remove oxygen. To coax the oxygen atoms away from the ore requires heat and an alternate atomic partner for the oxygen to bond to.Carbon fills this role nicely, and is readily available in the form of everyday charcoal, or coke, a form of carbon made from coal.
