Improved mineralogical analysis in copper ores by laser-induced breakdown spectroscopy

Abstract

Copper and its production process are crucial in the quest to achieve decarbonization of energy sources and electromobility. The quantification of mineral species in copper ores in real-time is important...

Atomic spectrometry update – a review of advances in environmental analysis

“…Fast and detailed analysis of mineral species in copper ores was achieved 198 by preliminary screening using hyperspectral imaging to discriminate between Cu-sulfides and barren minerals, followed by detailed elemental and mineralogical analysis by μLIBS. In a follow-up paper, multivariate calibration techniques such as PLS, ANN and MCR-ALS were compared 199 as quantification approaches for improved mineralogical analysis of copper ores. A new method was proposed 200 to overcome matrix interferences in the quantitative determination of total Fe in iron ores using variable-importance back-propagation ANN (VI-BP-ANN).…”
