CESTAT HYDERABAD Iron Ore fines vs lumps classification …
The case involved the classification of Iron Ore fines as Iron Ore lumps for export valuation and levy of export duty. The Tribunal held that the consignment, despite containing a certain percentage of Iron Ore lumps, should be treated as Iron Ore fines due to involuntary processes and the absence of deliberate mixing. The presence of Iron Ore ...

The IMSBC Code 2013
Iron ore and iron ore fines are two separate cargoes. Iron ore largely comprises lumpy material resembling small rocks or stones of 10-25 mm in diameter. It is defined as a category 'C' cargo under the IMSBC Code, meaning it is not liable to liquefy. Iron ore fines are largely made up of powdery material below

Iron processing
Sintering. Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together. For this purpose, a traveling-grate machine is used, and the burning of fine coke (known as coke breeze) within the ore generates the necessary heat.Before being delivered to the sinter machine, the ore mixture is moistened to cause fine particles to …

Furthermore, the classification of sintering conditions was achieved using affinity propagation (AP) clustering, while the support vector machine (SVM) algorithm was used to detect the conditions during sintering of iron ore fines. Different regression prediction algorithms were used to account for different conditions.

Comminution and classification technologies of iron ore
Hematite and magnetite, the two predominant iron ores, require different processing routes. High-grade hematite direct shipping ores generally only require crushing and screening to meet the size requirements of lump (typically between 6 and 30 mm) and fines (typically less than 6 mm) products.

Iron ore
The crushed ore is sorted over screens and resized to different specifications, such as lump and fines products. Once the iron ore is processed, a stacker builds a stockpile in the stockyards. When ready for transportation, a reclaimer picks up the ore from the stockpiles and conveys it to train load out facilities.

What are Iron Ore Fines? Iron ore is a natural/raw material that is mined around the world. The material is processed to allow its use in the iron/ steel making industry. Initially, this involves crushing followed by screening to separate the ore into lumps and fines. If the iron content of the processed ore is >60% then it can be shipped ...
