A common question raised by MineMine Managers is why do we need geometallurgyGeometallurgy, what are the costs and the benefits? GeometallurgyGeometallurgy is an interdisciplinary field that integrates geology, miningMining and metallurgyMetallurgy. Its purpose is to create predictive modelsModel for metallurgical behaviour before the ore is extracted. The aim is to fundamentally improve understanding of resource economics across the project. GeometallurgyGeometallurgy is a proven strategy for effective ore characterizationOre characterization and improved prediction of process variabilityVariability and can be used to enhance economics and reduce risk. GeometallurgyGeometallurgy can optimizeOptimize the life of a project. Implementing geometallurgyGeometallurgy requires planning and developing a database and inputting this into ore block modelsBlock models that display the distributionDistribution of key metallurgical parameters throughout the orebody that supports metallurgical process modellingModelling and adds value to the planning and optimizationOptimization process. A geometallurgical modellingModelling approach can directly reduce the risks in production stages, such as meeting the production targets. GeometallurgyGeometallurgy acts on both consequences and likelihood axes in reducingReducing the risk. This paper will delve into some important case studies where geometallurgyGeometallurgy has made breakthroughs in mineMine function and continues to be developed today, fostering innovation and productivity.
