Abstract
Method and its corresponding apparatus for unloading an iron ore in the form of a consolidated and hardened mass, loaded in the hold of a transport ship in the form of mud, characterized in that method by including the stages consisting of: dropping a jaw ladle provided with a pair of hollow ladle elements held in their open position, using their weight, on said hardened and consolidated mass contained in the hold of said transport ship to thereby undo said mass; closing said pair of hollow ladle elements to excavate said thus undone mass; and then raising said jaw ladle to discharge the thus excavated undone mass contained in said pair of hollow elements in their closed position.
