· Three bulk properties (type of cargo, moisture content, and pre-consolidation) are responsible for the variations of the dependent bulk properties. Various dependent bulk properties, including bulk density, angle of repose, penetration resistance, and shear strength were quantified.

· The three iron ore samples are categorized as very cohesive to cohesive based on the ring shear test results.

· A general conclusion is that the dependent bulk properties of cohesive iron ore samples are highly sensitive to the history of the applied stress, σ_pre. This phenomena was observed in both ring shear and consolidation-penetration tests, in which high correlations between pre-consolidation and respectively flowability and accumulative penetration resistance are found. Therefore, choosing appropriate range of pre-consolidation in the design of equipment for handling cohesive iron ore is also crucial.
