The additional step of concentrating iron ore will have environmental impacts, but the co-recovery of multiple products such as silica —in addition to concentrated iron ore — makes this approach worth exploring. "The cost of pre-concentrating may be higher, but the co-production of silica in addition to iron ore may unlock more revenues."

We have limited control over our Scope 3 emissions, as these come primarily from our customers in Asia while processing our iron ore into steel and bauxite into aluminium. While we have a key role to play, we do not set an overall Scope 3 emissions target as we have limited ability to directly influence the production processes of our customers ...

Iron ore is defined as a mineral deposit that contains iron minerals along with other minerals, and if it is economically viable to extract, it is considered as iron ore. It can be classified into different types such as magnetite, hematite, goethite, limonite, siderite, and others based on its mineral composition. ... (GHG) emissions, while ...
