16.1.2. Ore Banded-iron formations are an important ore of iron (Fe). Earth's materials include the periodic table elements. However, it is rare that these elements are concentrated to the point where it is profitable to extract and process the material into usable products.
During iron ore processing, accurately predicting the total iron (TFe) content in the ore is important for highly efficient and accurate sorting, which can reduce dust pollution, energy consumption, and economic losses, and promote waste utilization.
The iron and steel manufacturing sector directly accounts for 7–9% of global CO2 emissions. Raw material preparation, such as iron ore sintering, pelletizing, and cock making, is the major CO2 emitter. As climate change becomes a bigger concern, steel manufacturers need to lower CO2 emissions without hindering efficiency or increasing …
