Abstract
North American blast furnace ironmakers continue to extend campaign life with shotcreting techniques, hearth protection measures and stable operating practices. The Marcellus shale natural gas price reductions enhance the co-injection of natural gas with other injectants such as coal. Energy recovery cokemaking continues to advance while new formed coke production techniques are being explored. Iron ore developments include commercialization of plants to recover concentrate from iron ore tailings, building of new pellet plants and pellet plant expansions while existing pellet producers continue to improve quality. Iron unit production for the EAF sector progresses with pig iron nugget production as well as projects to restore gas based shaft furnace DRI production in the USA with these techniques continuing in Mexico and Canada.
