Abstract
Global iron ore production has grown dramatically in recent years to meet increasing world steel demand, especially in Asia. High grade lump ore resources are being depleted and a greater amount of fine concentrate/pellet feed will enter into production as lower grade deposits are mined. Integrated steel plants need to make convenient use of the available iron ore resources to optimize operation and the cost of steel. The advantages and disadvantages of using greater amounts of iron ore concentrate are discussed, focusing on the production and use of fired pellets in the blast furnace. Hot metal production using sinter and pellets in the blast furnace is compared, considering aspects like; blast furnace productivity, environmental performance, solid waste management, slag-coke rates, and the steel plant energy balance.
