The "ore group" iron ore textural classification scheme (Table 2.7 and Figures 2.7 and 2.8) has been developed to link ore texture to downstream processing performance including lump/fines ratio, beneficiation, blast furnace lump physical and metallurgical properties, or fine ore sintering quality (Clout, 2002). The Ore Group …
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 …
HAEMATITE IRON ORE-CLASSIFICATION ( Second Revision ) 1 SCOPE 1.1 This standard covers classification of haema- tife iron ore on the basis of composite minera- logy. 1.2 The standard is based only upon the main chemistry and the physical size of the end product. It envisages that any geological proto- ...
In this study, the algorithm of iron ore classification based on bilinear network is discussed, which can enhance the subsequent ore processing process. Firstly, the data set has been established by collecting the graphics of three types of iron ore and utilizing the data enhancement methods. Then, a modified bilinear network model based on cross …
Iron ore classification: Critical insights for resource. A powerful iron ore classification system is a critical prerequisite. Without a sufficiently and appropriately characterised resource, modelling will be inaccurate reducing an organisations ability to implement cost reductions and productivity gains across the iron ore value chain.
