This method for processing molten cast iron uses an inoculant that includes : 15-80 wt% of Si; as a rare earth element, either La of 80-100 wt% purity or Ce of 80-100 wt% purity; Ca; and Al; the remainder consisting of Fe and unavoidable impurities. The method includes a molten cast iron inoculation process, in which the inoculant is added to molten cast iron such that the amounts of the constituent elements added in relation to the molten cast iron are 0.001-0.009 wt% La or Ce, 0.001-0.02 wt% Ca, and 0.001-0.02 wt% Al.
