This involved a comprehensive study of the dominant banded iron formations units that cover 15 of the Vale iron ore mining projects in Brazil. The study comprised laboratory testing and petrophysical determination of proprieties of the different weathering horizons. Relationships were established between the petrophysical, rock strength and elastic arameters. The work concluded that each weathering horizon could be represented by typical parameters that can define a specific geomechanical behaviour, principally controlled by the iron content/bulk density, total porosity/permeability, and the mineral composition/band thickness. Ultimately, these parameters control the slope stability from shallow to deep iron ore mines.
