The iron and steel industry in China is suffering from the burden of overcapacity, structural adjustment and upgrading. In order to analyse and improve the energy efficiency, the life cycle energy consumption and greenhouse gas (GHG) emissions of iron pelletizing are estimated in this work. The direct energy consumption is 793.4 MJ/t, with the largest energy …

Loss on ignition (LOI) in the mineral represents the chemically bonded water which can be removed at high temperatures only. High LOI in iron ore fines has an adverse affect during pellet induration process. High-LOI iron ore fines are required for detailed laboratory pelletization studies and are used in pellet making. The received iron ore is martite–goethitic and …

Iron is produced by smelting iron ore with a high-carbon fuel and reductant such as coke (coking coal), usually with limestone as a ˚ux (to reduce the temperature at which the iron melts). Most crude steel is produced in a basic oxygen furnace where molten iron (from the blast furnace) is combined with steel scrap (<30%) and small amounts of ˚ux.
