Abstract [en]

Geometallurgy combines geological and metallurgical information to create spatially-based predictive model for mineral processing plants. A review of how geometallurgy is currently applied in mining industry shows that the linkage of geological information and metallurgical response relies on small number of samples tested in laboratory. Therefore a holistic particle-based approach is proposed. The particle-based approach uses minerals and particles as a common parameters going through the geometallurgical program from the collecting of the geological data to the process simulations. The approach consists of three quantitative models: 1) geological model, 2) particle breakage model and 3) unit process models. The geological model describes quantitatively and spatially modal composition and texture of the ore. The particle breakage model that describes quantitatively what kind of particles will be produced as the rocks given by the geological model are broken. The unit process models quantify how particles behave in different unit operations. For developing and managing the models some practical techniques are described and proposed. Finally the models are combined in a simulator which is used to run the process simulation and derive process performance parameters for each ore block individually. The process performance parameters include figures like throughput; energy consumption; concentrate recovery and grade; and tailing properties. Finally a practical example from Kemi chromite mine is given.
