Four size ranges of IOTs depicted as IOTs-Fine IOTs-1180 IOTs-600 and IOTs-425 were investigated in this study. During iron ore mining operations two types of IOTs are generated fine IOTs and coarse IOTs. The fine iron ore tailings as obtained from the mine without additional processing are named IOTs-Fine in this study.
