How is iron ore mined? From pit to port, our iron ore undergoes a series of processes before export. First, we explore the geology of the region to find the best iron ore prospects for our operations. Once the ideal site has been chosen, the ore is drilled and blasted. It is then transported to the primary crusher for processing.
