Application of pre-magnetic separation to address grinding
Adding a pre-magnetic separation process to the ore beneficiation process separates magnetic and non-magnetic minerals with significant differences in performance before grinding, allowing for a more targeted grinding process to address the "density effect" in magnetic iron ore grinding and classification.

Iron ore
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.
