There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, through to deep purple, rusty red and bright yellow. Iron is responsible for the red colour in many of our rocks and the deep red sands of the ...

The ore texture is mainly observed under a microscope, and some coarse particles can also be observed with naked eyes. The ore structure and texture are collectively referred to as ore fabric. Through the study of ore fabric, the ore genesis can be understood scientifically and the deposits can be evaluated properly from an industrial …
The source of iron ore originates from the iron-rich sedimentary rocks where iron is commonly found in the form of hematite (Fe 2 O 3, 70% Fe), magnetite (Fe 3 O 4, 72% Fe), siderite (FeCO 3...
In an iron ore pelletization plant, pellets are produced inside a rotating disc pelletizer. Online pellet size distribution is an important performance indicator of the pelletization process.
Due to the complexity of, and low accuracy in, iron ore classification, a method of Laser-Induced Breakdown Spectroscopy (LIBS) combined with machine learning is proposed. In the research, we collected LIBS spectra of 10 iron ore samples. At the beginning, principal component analysis algorithm was employed to reduce the …

Mineral - Classification, Properties, Types: Since the middle of the 19th century, minerals have been classified on the basis of their chemical composition. Under this scheme, they are divided into classes according to their dominant anion or anionic group (e.g., halides, oxides, and sulfides). Several reasons justify use of this criterion as …
Results of experiments indicate that it is possible to detect the operating state of the pelletization disc by acquiring images from the inside area of the disc with sufficient accuracy. In an iron ore pelletization plant, pellets are produced inside a rotating disc pelletizer. Online pellet size distribution is an important performance indicator of the …
In this paper, the rock types of an iron ore deposit were classified using the digital image analysis technique. The image acquisition and analysis of blasted rocks were conducted in a laboratory for six different rock types. A total of 189 features were extracted from the individual rock samples using best-suited segmentation technique selected by …
