“…Currently, several techniques have been introduced to capture the 3D particle geometries by various 3D imaging systems, including RhoVol, stereo photography, X-ray CT, 3D laser scanning, white light scanning [19][20][21][22]. Some application of 3D imaging techniques in mineral processing is summarized as follows (Table 1): -crack density, rock characteristics -intergranular fracture and crack surface area during multiphase particle breakage in comminution operations [25, 26] [27, 28] Quantitative characterization of pore size and structural features [29] -Mineral liberation and grade grade-recovery curves -Exposed grain surface area [17,30,31] [32, 33] Density [16,22] This paper summarizes the publications and findings from 2015 to 2023 regarding the advances and applications of 3D imaging technology in the field of mineral processing. The existing technologies, such as high-speed scanning and image analysis techniques to measure significant particle characteristics, such as size, shape, volume, density and composition are introduced.…”
