Powdery iron ore includes the concentrate and natural rich ore produced by fine grinding separation. Iron ore powder agglomeration is the basis for blast furnace ironmaking and is the processing work in between ore crushing, ore grinding separation, and steelmaking. Its purpose is to provide high-quality furnace burden for steelmaking.
Compliance with local regulations and environmental standards is a prerequisite for any industrial operation, including iron processing plants. Costs associated with obtaining permits, conducting environmental impact assessments, and implementing mitigation measures should be factored into the overall project budget.
For this purpose, in 2019, a total of 2315,7 Mta iron ore with an iron mineral content of 1436 Mta and an average iron content of 62.0 % was used. The most important iron ores are haematite (Fe 2 O 3 ) with up to 69.9 % iron content, magnetite (Fe 3 O 4 ) with up to 74.2 % and siderite (FeCO 3 ) with up to 48.2 % iron content.
