Classification of iron ores by laser-induced breakdown ...

The classification and recognition of the iron ore grade were completed using their chemical properties and compositions. In addition, two parameters of the RF were optimized using out-of-bag (OOB) estimation. Finally, support vector machines (SVMs) and RF machine learning methods were evaluated comparatively on their ability to predict unknown iron ore samples using models constructed from a ...

Optical image analysis for textural ore classification ...

Ore classification by mineral and textural type is a critical method for predicting the behaviour of iron ore fines during beneficiation and in sintering and pelletising agglomeration processes. In current industry practice, chemistry (or ore grade) is the primary measure of ore quality. However, classifying ores through grade alone doesn’t guarantee product quality or consistency later in ...

Ore - Wikipedia

Ore is natural rock or sediment that contains desirable minerals, typically metals, that can be extracted from it. Ore is extracted from the earth through mining and refined, often via smelting, to extract the valuable element or elements.. The grade of ore refers to the concentration of the desired material it contains. The value of the metal an ore contains must be weighed against the cost ...
