  Predicting TFe content and sorting iron ores from …

  2023121 · Therefore, this paper explored it. For the experimental materials, 150 high-grade and 150 low-grade ore samples with particle sizes ranging from 20 to 40 mm were prepared. Subsequently, hyperspectral images of these samples were acquired within the range of 953–2517 nm, and the TFe content of each ore sample was measured.
