Classification of Iron Ore Particle and Relationship between Those Mineral Characteristics and Sintering Properties

Australian hematite iron are particles were rinsed with clear water, and classified from its color into three types; yellow particles, intermediates particles, and black particles. Then (1) investigation of the basic properties of the particle according to the iron ore type, (2) the melt examination, and (3) the sintering pot test were executed. As a result, each classified type of iron are particle showed a similar mineral characteristic and sintering result was controlled greatly by their ratios. It was clarified that the inferior sintering result for the MarraMamba ore was mainly caused by the higher ratio of the yellow particles.
