Geometallurgy utilises geological and mineral processing information to capture the spatial metallurgical characteristics of the ore body. Mineralogy-based geometallurgical modelling employs quantitative mineralogical information, both on the deposit and in the process. The geological model must describe the minerals present, give their ...
