Descrição: dc.descriptionThis work explores the use of LiDAR sensor technol ogy as a non-contact method for real-time ore mass measurement in ore processing plants. The ore produced is stored in product yards in organized piles based on quality specifications and later transported through a circuit of yard machines, conveyor belts, and a loading silo. After filling the silo, wagons are loaded and their mass is measured using the railway scale. Inventory is determined either by topographical survey or conveyor belt scales. Discrepancies between measurements from belt scales and railway scales can cause inventory breakdown. Furthermore, traditional mass measurement systems have limitations due to physical constraints, besides the need for mechanical adjust ments and recalibrations that interrupt processes. To overcome these challenges, this study suggests using LiDAR sensors. The proposed solution involves installing LiDAR sensors over the belt conveyors feeding the loading silo entrance. This allows for real-time integration of the ore area passing through and, with known density, enables the calculation of its volume and mass on the belt. Comparisons between LiDAR measurements and existing scales were statistically tested with field measurements, showing a significant similarity at a 5% significance level. The results demonstrate that LiDAR technology provides a viable and accurate alternative or complement to traditional mass measurement systems in ore processing plants. This method offers flexibility in installation points, eliminating the need for constant mechanical adjustments and recalibrations, enhancing measurement accuracy in the loading circuit. Furthermore, potential applicability of LiDAR can be extended beyond ore processing. Index Terms—Conveyor Belts, LiDAR-
