The reduction gases only dissolve oxygen from the iron ores. This causes the iron ores to crack on the surface. The appearance resembles a porous sponge, which is why the deoxidized and thus strongly ferrous iron ore is also called sponge iron. Sponge iron is a highly ferrous ore from the direct reduced iron process!
Iron ore is a mineral that is a source of metallic iron extracted through mining. The extraction and processing of iron ore result in the generation of significant amounts of solid and liquid waste, including tailings containing various toxic metals.

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.
In hard rock mining, much of the world's annual output of copper, gold and iron ore is won from open-pit operations.
