Among them, the dissemination characteristics of minerals refer to the particle size, shape and the combination relationship between minerals in the ore.
Effect of particle size on pellet quality during pellet making has also been aimed and studied along with the development of flowsheet for beneficiation of low grade iron ore.
Moreover, quantitative analysis of coke breeze in a quasi-particle was carried out. The results obtained are follows: (1) Regardless of the brand of iron ores and existence of nuclei, the quasi-particle diameter became smaller when coke breeze was added and it became smaller when the particle size of coke breeze became larger.
