摘要

Laser-Induced Breakdown Spectroscopy (LIBS) is gaining significant traction in the mining industry as a powerful tool for rapid, non-destructive elemental analysis with minimal sample preparation. This paper presents a comprehensive overview of the current and emerging applications of LIBS across the mining value chain, including mineral identification, ore grade control, geochemical exploration, and process optimization. The integration of LIBS with machine learning algorithms and autonomous platforms has enhanced its potential for real-time, in-situ analysis, offering enhanced decision-making and improved operational efficiency. Moreover, LIBS contributes to environmental monitoring by enabling on-site detection of hazardous elements, thus supporting compliance with environmental regulations. While the technology faces certain limitations – such as calibration complexity, sensitivity variation, and equipment cost – ongoing advancements in laser systems, spectrometer design, and miniaturization are steadily overcoming these barriers. By comparing LIBS with conventional analytical techniques, the paper underscores its advantages in speed, portability, and adaptability. The discussion also highlights future research directions and technological trends that position LIBS as a key enabler for sustainable and data-driven mining practices.
