Here are three actions they should consider taking. Accelerate highgrade production. Iron ore mining companies already prioritize the production of betterquality ores, but they need to do more. Ores with more iron content and fewer impurities enable manufacturers to produce highervalueadded green steel efficiently.

Download Iron (Fe) is a metallic element that constitutes % by weight of the Earth's crust and is the fourth most abundant element in the crust. Iron ores are rocks from which metallic iron can be economically extracted. The principal iron ores contain hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ). Hematite is an iron oxide mineral.

Increased mining activity of iron ore has led to the generation of voluminous wastes of various nature, especially during the different stages of its extraction and production. The improper disposal of such waste causes negative impact on the environment. One such waste which is generated during the beneficiation process of iron ore is waste iron ore tailings, which is also termed as IOT.
