Iron ore (fines)

Iron Ore (fines) Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe 3 O 4 ), hematite (Fe 2 O 3 ), goethite (FeO (OH)), limonite ...

Detection and segmentation of iron ore green pellets in images .

 · In steel manufacturing industry, powdered iron ore is agglomerated in a pelletizing disk to form iron ore green pellets. The agglomeration process is usually monitored using a camera. As pellet size distribution is one of the major measures of product quality monitoring, pellets detection and segmentation from the image are the key steps to determine the pellet .

The Sintering Process of Iron Ore Fines – IspatGuru

 · Sintering process helps utilization of iron ore fines (010 mm) generated during iron ore mining operations. Sintering process helps in recycling all the iron, fuel and flux bearing waste materials in the steel plant. Sintering process utilizes by product gases of the steel plant. Sinter cannot be stored for a long time as it generates excessive fines during long storages. .
