Figure 1 shows the Fe and gangue contents in the iron ores from different deposits of the major iron ore producing nations and from Muko deposit of Uganda. In this figure, the total gangue content was determined as the sum of SiO 2 and Al 2 O 3 contents in iron ores. All the iron ores were divided into three groups according to the total Fe and gangue content.
