| description | Coarse gangue rejection (CGR), a method utilized for ore upgrade by physical methods (screens and
density) or sensor-based detection, has become highly topical in the modern mining value chain.
However, selecting an ore suitable for such an approach has been the main setback for its more
comprehensive application. Despite the advancement of technology, characterization for ores amenable
to coarse gangue rejection is still limited, mainly in the gold sector. The current declining nature of ore
grade and the emergence of complex ores have made ore characterization more critical. Currently,
during deposit development and mining operation, ore characterization is an integral component of
the process. It provides a great deal of information about an ore, contributing to overall process
performance prediction and managing uncertainties in mineral processing plants. As for every other
mineral processing unit operation, ore characterization for coarse gangue rejection helps understand
the inherent properties of ore that influence the separability of the product stream. In light of this, this
paper looks at a brief review of ore characterization methods that have been utilized in literature for
identifying ores that are amenable for coarse gangue rejection and assesses the opportunities available
for further improvement to the methodology. The advancement in geometallurgy has seen ore
characterization shifting toward more comprehensive geometallurgical approaches. Identifying
geometallurgical parameters indicating CGR performance before conducting complete CGR
characterization is seen as a vital tool in driving future CGR characterization methods. |
