Detailed mineralogical characterization study has been conducted on low grade iron ore sample from Bellary-Hospet region, Karnataka, India by using XRD, optical microscopy and Möss ...
A total number of 189 features, including 49 textural, 112 colours and 28 morphological features was extracted from individual rock samples. These features were used as the basic inputs for the modelling of rock-type Rock type classification of an iron ore deposit 35 classification.
In the processing of ore extracted from banded iron formations, comminution unit operations generally encounter ore variability challenges as discussed in more technical detail (in e.g., Gomes et ...
The article provides an overview of the steel making process, detailing how raw materials like iron ore, coke, and limestone are transformed into versatile and durable steel through a complex series of steps depicted in a …
Iron ore pellets are marble-sized balls of iron ore that are fused with clay for transportation and used in steel manufacture. The process of making pellets from iron ore is called pelletizing. The manufacture of steel from low-grade iron ore involves processes like mining, crushing, separating, concentrating, mixing, pelletizing, and shipping.
The classification of iron ore rock plays a crucial role in assisting the mine to develop scientifically sound mining strategies. Given the limitations of traditional manual identification and chemical techniques in terms of cost and detection time, it is crucial to develop an economical, high-precision, and efficient classification method for iron ore rocks.
CITATION:Nunna, V, Hapugoda, S, Gaekwad Eswarappa, S, Raparla, S K, Kumar, R and Nanda, N K, 2019. Dry beneficiation of low-grade goethite-rich iron ore fines by air classification, reduction roasting and magnetic separation, in Proceedings Iron Ore 2019, pp 766785 (The Australasian Institute of Mining and Metallurgy: Melbourne).
With a texture-based iron ore classification, you are able to understand the porosity, physical properties, mineral proportions and mineral associations of ores, increasing the efficiency of downstream processing and allowing proactive response to changing feed type.
Classifying iron ore at the resource drilling stage is an area where automated lithology classification could offer significant benefits in the efficiency of mine planning and geo-metallurgical studies. Presently, iron ore lithology and grade are classified manually from elemental assay data, usually collected in 1–3 m intervals.
